I need help with my social statistics homework!

For questions 1 through 8, determine what the appropriate test you would use is. You do not have to test the hypothesis for these questions. Possible variance, dependent sample t-test, or z-test for proportions Answers: Independent sample t-test with equal variance, independent sample t-test with unequal Are new doctors more likely to make medical errors (21 %) than experienced doctor (11%)?
