The final result gives the chi-squared (χ²) test value of 1.15 with 3 degrees of freedom. Consulting the Table of χ² Critical Values and a level of significance α=0.05, we obtain a critical value of 7.81.
Since the chi-squared value of 1.15 is less than the critical value of 7.81, the null hypothesis is ACCEPTED.
Your lab partner completed a chi-squared (χ²) test on your lab data (above) for the F2 generation in a standard dihybrid cross. The goal was to verify if the observed results matched the expected phenotype ratios.
However, it appears they made an error. What did they do wrong?
A. The expected progeny for the null hypothesis is incorrect. They did the calculation wrong. Incorrect B. The wrong rejection criteria was used. the significance level, α is wrong. Incorrect C. The degrees of freedom is wrong, it should be a different value. Incorrect D. The numbers in the calculation have to be squared and they are not squared. Incorrect E. The wrong numbers in the calculation were used for division, you need to divide by a different number. Correct MCf821_74ac
