A high school biology class conducted genetics experiments with randomly selected fruit flies, and the results in the following table are based on the results that they obtained. Use a 0.05 significance level to test the claim that the observed frequencies agree with the proportions that were expected according to principles of genetics. Characteristic Red Eye/ Normal Wing Sepia Eye/ Normal Wing Red Eye/ Vestigial Wing Sepia Eye/ Vestigial Wing Frequency 70 19 18 5 Expected Proportion 9 / 16 3/ 16 3/ 16 1/ 16 Determine the null and alternative hypotheses. Ho: Calculate the test statistic, x x2 = (Round to three decimal places as needed.) Calculate the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? Because the P-value is the significance level, Ho. There sufficient evidence to warrant rejection of the claim that the observed frequencies agree with the proportions that were expected according to principles of genetics.
