1. A health clinic wanted to figure out if their two-month diet program is effective for losing weight. To test this claim they recorded the before and after weight of seven of their patients. Which hypothesis test should the health clinic conduct to determine if their two-month diet program is effective? (Circle the best answer) a. One-Sample t-test Independent Two-Sample t-test Paired Sample t-test After running the hypothesis test, the health clinic obtains the following output: HD H1 - H2: Mean of the difference between Beforg and After Ho: Hp-0 HA : HD >0 Hypothesis test results: Difference Mean Std. Err. DF T-Stat P-value Before - After 5.2857143 2.7054996 6 1.9536925 0.0493 b Using a 5% significance level, does the clinic reject Ho or fail to reject H,? Explain your reasoning.
