Give four methods for determining whether the sample data come from a normal population.
Answer to relevant QuestionsWhat is a normal probability plot and how is it used? Scientists at GlaxoSmithKline Medicines Research Center used high-performance liquid chromatography (HPLC) to determine the amount of drug in a tablet produced by the company (Analytical Chemistry, Dec. 15, 2009). Drug ...Assume that x is a binomial random variable with n = 1,000 and p = .50. Find each of the following probabilities: a. P(x > 500) b. P(490 ≤ x < 500) c. P(x > 550) Use Table V in Appendix A to determine the value of e -a/u or each of the following cases: a. θ = 1, α = 1 b. θ = 1, α = 2.5 c. θ = .4, α = 3 d. θ = .2, α = .3 Assume that x is a random variable best described by a uniform distribution with c=40 and d=70. a. Find f(x). b. Find the mean and standard deviation of x. c. Graph the probability distribution for x, and locate its mean ...
