Question

Independent random samples of n₁ = 100 and n₂ = 100 observations were randomly selected from binomial populations 1 and 2, respectively. Sample 1 had 51 successes, and sample 2 had 56 successes.

b) Calculate the standard error of the difference in the two sample proportions, (p̂₁ − p̂₂). Make sure to use the pooled estimate for the common value of p. (Round your answer to four decimal places.)

d)p-value approach: Find the p-value for the test. (Round your answer to four decimal places.)
p-value =

(e) Critical value approach: Find the rejection region when α = 0.01. (Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused region.)
