Question

Assume that you plan to use a significance level of a= 0.05 to test the claim that p₁ = p₂ . Use the given sample sizes and numbers of successes to find the P-value for the hypothesis test.

n₁ = 50

x₁ = 8

n₂ = 50

x₂ = 7

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
