Question

a. Test the following hypotheses of the difference in population means by using the following data (α = .10) and the eight-step process.
H0: µ1 - µ2 = 0 Ha: µ1 - µ2 < 0

Sample 1 ..... Sample 2
n1 = 31 ... n2 = 32
x̄1 = 51.3 .... x̄2 = 53.2
σ21 = 52 .... σ22 = 60

b. Use the critical value method to find the critical difference in the mean values required to reject the null hypothesis.
c. What is the p-value for this problem?
