Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 21.044 is correct and we REJECT the null hypothesis (H0) Correct Table 2 with χ² = 0.756 is correct and we REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.405 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 21.044 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 0.756 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.405 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC3741_4736

Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 0.511 is correct and we REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 3.778 is correct and we REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 2.952 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 0.511 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 3.778 is correct and we FAIL to REJECT the null hypothesis (H0) Correct Table 3 with χ² = 2.952 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC4e71_6d13

Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 0.756 is correct and we REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 15.444 is correct and we REJECT the null hypothesis (H0) Correct Table 3 with χ² = 0.432 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 0.756 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 15.444 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.432 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC06a6_4f1c

Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 15.244 is correct and we REJECT the null hypothesis (H0) Correct Table 2 with χ² = 0.778 is correct and we REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.482 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 15.244 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 0.778 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.482 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC535f_2f4c

You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 12.401 is correct and we REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 16.711 is correct and we REJECT the null hypothesis (H0) Correct Table 3 with χ² = 0.911 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 12.401 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 16.711 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.911 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC92f3_6885

Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 0.413 is correct and we REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 13.267 is correct and we REJECT the null hypothesis (H0) Correct Table 3 with χ² = 9.856 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 0.413 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 13.267 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 9.856 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MC591a_7cf4

Your lab partner is trying again (eye roll) and did another a chi-square (χ2) test on the F2 generation in a dihybid cross based on your lab data (above). They wanted to know if the results confirm the expected phenotype ratios.
You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 0.422 is correct and we REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 1.944 is correct and we REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 20.844 is correct and we REJECT the null hypothesis (H0) Correct Table 1 with χ² = 0.422 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 1.944 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 20.844 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MCa55b_46f1

You helped them set up the null hypothesis (H0), so you know that part is correct, but they got confused and were unsure about how to calculate the chi-square statistic (χ2). So much so that they did it three (3) different ways.
Before you ask your instructor for a new lab partner, tell them which table is correct AND whether they can reject or fail to reject the null hypothesis (H0) using the information provided.
Table 1 with χ² = 16.911 is correct and we REJECT the null hypothesis (H0) Correct Table 2 with χ² = 0.889 is correct and we REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.467 is correct and we REJECT the null hypothesis (H0) Incorrect Table 1 with χ² = 16.911 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 2 with χ² = 0.889 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect Table 3 with χ² = 0.467 is correct and we FAIL to REJECT the null hypothesis (H0) Incorrect MCbaf8_ce98
The table below gives chi-square critical values for each probability in the right tail.
