onsider the hypothesis test below.

H0: p 1 - p 2 ≤ 0
Ha: p 1 - p 2 > 0

The following results are for independent samples taken from the two populations.

Sample 1 Sample 2
n1 = 200 n2 = 400
p1 = 0.23 p2 = 0.16
  1. What is the value of the test statistic (to 2 decimals)?

  2. What is the p-value (to 4 decimals)?

  3. With α = .05, what is your hypothesis testing conclusion?
