Use a = 0.10. For correct grading, use d = before - after. 1. The population distribution requirement for this test is: O Need a normally distributed population O None needed The hypotheses are: O Ho:µ1 2 p2; Ha: µ1 < p2 %3D O Ho: 1 = 42; Ha: µ1 42 0 < Prt :0 > Prt O 0> Prt :0 Z Prl O O Ho: H S H2; Ha: u1 > 42 2. This is a CO rightO leftO two tailed test and the test used is a: O Paired T-Test (dependent populations) O2-Sample T-Test (independent populations) O2-Sample Z-Test (independent populations) The Degrees of Freedom (If needed, use the simple estimate discussed in the notes, not the messy formula) are
