Unformatted text preview: 1 Homework 4 (9 pts) due Sept. 23 (1 pt) 2.45 (use SAS) The following are modulus of elasticity observations for cylinders given. 37 37.5 38.1 40 40.2 40.8 41 42 43.1 43.9 44.1 44.6 45 46.1 47 62 64.3 68.8 70.1 74.5 Use the quantiles for a sample of size 20 given in this section to construct a normal quantile plot, and comment on the plausibility of a normal population distribution. CODE: data problem2_45; input elasticity @@; datalines ; 37.0 37.5 38.1 40.0 40.2 40.8 41.0 42.0 43.1 43.9 44.1 44.6 45.0 46.1 47.0 62.0 64.3 68.8 70.1 74.5 ; run ; proc univariate data =problem2_45; qqplot elasticity; run ; GRAPH: This is not linear, so it is not plausible that this data set is normal. 2 (0.5 pts.) 5.18a (p.210). Suppose that the frequencies of blood phenotypes in the population are as follows: A B AB O 0.42 0.10 0.04 0.44 a) What is the probability that two randomly chosen people both have blood type A? P(person 1 = A and person 2 = A) = P(person 1 = A) * P(person 2 = A) [assuming that the blood type of one person is independent of the blood type of the second person] (0.42)(0.42) = 0.1764 (0.5 pts.) 5.42 (p.228). What primary purpose do sampling distributions serve in statistical (0....
