In assessing data that fell into two phenotypic classes, a geneticist observed values of 20:150. She decided to perform a Chi-Square (X) analysis by using the following two different null hypotheses: a) the data fit the 3:1 ratio, and b) the data fit the 1:1 ratio. Calculate the Chi-Square (x) values for each hypothesis. What can be concluded about each hypothesis?
