Consider the following hypothesis test:

H₀: 1 2 = 0.5

H_a: 1 2 0.5

Two random samples are selected from two populations with means ₁ and ₂, respectively. The sample sizes, sample means, and population standard deviations are shown below. Use = 0.05.

Sample 1: n 1 = 40; x 1 = 7; 1 = 3

Sample 2: n 2 = 60; x 2 = 6; 2 = 1
