Suppose the accompanying summary statistics for a measure of social marginality for samples of youths, young adults, adults, and seniors appeared in a research paper. The social marginality score measured actual and perceived social rejection, with higher scores indicating greater social rejection. Age Group Youths Young Adults Adults Seniors Sample Size 101 255 313 36 2.00 3.20 3.07 2.82 S 1.56 1.68 1.67 1.89 For purposes of this exercise, assume that it is reasonable to regard the four samples as representative of the U.S. population in the corresponding age groups and that the distributions of social marginality scores for these four groups are approximately normal with the same standard deviation. Is there evidence that the mean social marginality scores are not the same for all four age groups? Test the relevant hypotheses using a = 0.01. Calculate the test statistic.

Question
Is there a quick way to solve these kinds of problems with a TI-84? I spend a lot of time doing them by hand and I desperately need to speed up the process. Can you please walk me through the steps I need to do?
please do not use excel, I will not have access to that.
