Assignment:
T-test
T-tests compare two groups. For each question, please divide your independent variable into two groups. I expect a statement regarding which variables you used to as the dependent and independent variables to answer the question, a description of how you divided your groups, the means of the groups, the t-value, and the significance. You also need to interpret these results.
Remember: Use the correct values (can equal variances be assumed?)
The significance is given as a two-tailed result. Is this the result you should report?
