Question: Independent Samples t-test

? Choose any scale variable and any nominal variable with two levels from the RENAL.sav file (e.g., GENDER, DIABETES, ALIVE, BYPASS, etc.).

? Write out the assumptions for the Independent Samples t-test and evaluate that the variables are appropriate for the test (if not, you must select another set of variables).

? State the hypothesis to be tested.

? Test for the equality of variances before proceeding.

? Conduct an Independent Samples t-test on the scale variable with the nominal variable as a grouping variable.

? State the reject / not reject decision and conclusion.

? State any insights (in English) you can draw from the results; if you reject the null, your insights should follow from the conclusion, and if you fail to reject the null, then your insight should be non-conclusive but possibly offering thoughts about why the results were as they were and whether it makes intuitive sense.
