Consider the hypothesis statement to the right using =0.10 and the data to the right from two independent samples.

H₀: ₁₂0

H₁: ₁₂>0

x₁=88 x₂=74

₁=21 ₂=18

n₁=50 n₂=60

a) The test statistic is =3.71

The criticalvalue(s) is =1.28

Since the test statistic falls in the rejectionregion, reject H₀. There is sufficient evidence to conclude that the mean of population 1 is greater than the mean of population 2.

b) Thep-value is =0.000

Since thep-value is ? , ? H₀. There is ? evidence to conclude that the mean of population 1 is less than the mean of population 2.
