Hypothesis Testing: Type A Personalities
Assume that the subject population for whom data are reported are all Type A personalities. The hypotheses being tested were 1) whether there was a difference in DBP risk as a function of increasing age, 2) whether there was a difference in DBP as function of gender, 3) Whether Type A men and women show the same pattern of DPB across age groups. This brings in the possibility of a statistical interaction.
The data are attached. I have included a graph of the Age by Gender means. I think it will give you a good visual indicator of what is going on in the interaction.© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/statistics/hypothesis-testing/hypothesis-testing-type-a-personalities-j80g
