Describe the following sampling distributions. What are the means and standard errors, and are we guaranteed of normality? a. µ = 20; σ = 4; n = 64 b. P = 70%; n = 30

Question

must show all work and calculation please!

Answer 1

a. mean is 20 SE is 4/sqrt(64) = 0.5

b. mean is 0.7 SE is sqrt(0.7 * 0.3/30) = 0.084
