Chapter 0, Problem 12.12(choose chapter or problem)
A certain genetic characteristic of a particular plant can appear in one of three forms (phenotypes). A researcher has developed a theory, according to which the hypothesized proportions are p1 .25, p2 .50, and p3 .25. A random sample of 200 plants yields X2 4.63. a. Carry out a test of the null hypothesis that the theory is correct, using level of significance a .05. b. Suppose that a random sample of 300 plants had resulted in the same value of X2 . How would your analysis and conclusion differ from those in Part (a)?
