The degenerative disease osteoarthritis most frequently affects weight-bearing joints such as the knee. Two random samples from two different age categories are collected, and the following summary data on stance duration is presented. It is assumed that both age categories have equal population (true) variances.
Age Category Sample Size Sample Mean Sample Standard Deviation
Age Category 1 13 810 67
Age Category 2 19 770 56
Test the hypothesis that the mean of age category 1 is greater than the mean of age category 2 at 5% significance level.
Calculate P-Value.
