2. An individual is heterozygous for an inversion chromosome as shown below: Q R S T E F G H Q R S 9 3 1 H A. Draw the looped arrangement of the chromosomes that you would expect to see when they are paired for meiosis I. (Although there are four strands present at meiosis I, only two are shown here; you need only draw two strands). B. Assume...

Let X1, X2, ..., X9 be a sample of Normal random variables with expectation μ=72 and variance σ2=49. (Namely, standard deviation of σ=7.) Consider the statistic T = (X-72)/[S/ √9], where X is the sample average and S2 is the sample variance. The probability P(T ≤ 2) is best described by: Select one: a. 0.95 b. 0.96 c. 0.97 d. 0.98
