Suppose the agronomist is considering two possible genetic mechanisms for the inheritance of resistance; the population ratio of resistant to susceptible progeny would be 1:1 under one mechanism and 3:1 under the other. If the agronomist uses the sample size determined in Exercise 9.2.12, can he be sure that a 95% confidence interval will exclude at least one of the mechanisms? That is, can he be sure that the confidence interval will not contain both 0.50 and 0.75? Explain.
