Q1) In 1,000 samples, suppose that H0 is true, how many times would you expect to cause Type I error if (a) α = .05, (b) α = .01, and (c) α = .001.

Q2) Compute test statistic and p-value for each sample. (Negative amount must be pointed out by minus sign.)

i) H0: π ≤ .60 versus H1: π > .60, α = .05, x = 56, n = 80

ii) H0: π = .30 versus H1: π ≠ .30, α = .05, x = 18, n = 40

iii) H0: π ≥ .10 versus H1: π < .10, α = .01, x = 3, n = 100
