You do some research and find that a census of Ireland in the1910s found 65 individuals afflicted with cystic fibrosis out of100,000 people. You want to investigate whether the gene involvedin cystic fibrosis is under Hardy-Weinberg equilibrium. To do this,you use the frequencies observed in the present to determine theexpected number of individuals in each class in the 1910 study.
Frequencies observed in the present: p=.97 , q=.03
Fill in the following table (2 points):
CC
Cc
cc
Total
Expected number of individuals (i.e. numbers based onpresent dataset)
100,000
Observed number of individuals in 1910
65
?² =
Use the ?² table provided below to infer thep-value of the test (0.5 points)
Reminder: the p value is found by cross referencing the?²value with the critical value. For example, if your?² value is 5.34 and the degree of freedom is 1, youwould say 0.05 > p-value> 0.01.
Can you conclude that the gene involved in Cysticfibrosis is in Hardy-Weinberg Equilibrium with 95% certainty?Explain why or why not in a sentence or two. (0.5point)
