Place the correct alphabet (a, b,c, d) before your answer 7 Multiple Choice. Circle the most appropriate answer A. There were 3 populations of lemmings in Squaw Valley. Strain A overlapped strained B by 20% and Strain B overlapped Strain C by 10%. There was no overlapping between Strains A & C. In testing hypotheses between Strain A and the other two strains (B&C; 1.

Sol: For a hypothesis test, P(type II error), beta, depends on the value of the test satistic. Here, for A and C, the overlap is small, so the test staistic would be smaller for the hypothseis test of A vs C. The smaller the test staistic is, greter is the probabilty of rejecting the null hypothesis, or smaller the probablity of a type II error. Power of the test, (1 - beta), in that case, would bve greater. So, option 5. Both 3 and 4 are correct, is the correct option.
