Question

The degenerative disease osteoarthritis most frequently affects weight-bearing joints such as the knee. Stance duration was measured in seperate samples of younger and older adults. Test the claim that the true average stance is different between younger and older adults

Younger: n = 22, xbar = 801, s =117

Older: n = 16, xbar = 780, s = 81

Let population 1 = younger

population 2 = older

what is the appropriate procedure to test the claim?

what is the degrees of freedom? Use the conservative formula

At 0.05 significance level, what is/are the critical value/s?

what is the value statistic?

what is the margin of error?

does the result of the confidence interval estimate aggrees with the hypothesis test
