A priori alpha = 0.05
Group 1 (Mean = 34.4, SD = 5.6)
Group 2 (Mean = 28.4, SD = 10.78)
Independent t-test results: p value = 0.07
Are these groups statistically different?

Solutions

Expert Solution

H0: mu1 = mu2

Ha: mu1 not equals mu2

p-value = 0.07 and alpha = 0.05

As p-value > alpha, fail to reject H0

This is means these groups are not statistically different
