Test the claim that on average, people lost over 10 pounds on the diet. Use a = 0.05. For correct grading, use d = before - after. %3! 1. The population distribution requirement for this test is: O None needed O Need a normally distributed population The hypotheses are: O Hd S 10; Hd > 10 O Ho: µ1 = 42; Ha:µ1 # µ2 O ud 2 10; ud < 10 O Ho:µ 2 42; Ha:µ1 < µ2 O Ho:41 S H2; Ha:µ1 > µ2 O Hd = 10; µd # 10 2. This is a C twoO leftO right tailed test and the test used is a: O2-Sample Z-Test (independent populations) 2-Sample T-Test (independent populations) Paired T-Test (dependent populations) The Degrees of Freedom (If needed, use the simple estimate discussed in the notes, not the messy formula) are
