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 Before 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
Using a 5% significance level, does the clinic reject Ho or fail to reject H,?
Explain your reasoning.

If we wanted to use a 5% significance level create a confidence interval to
approximate our parameter, what should our level of confidence be? (Hint: First
determine the type of test we have by looking at your alternative hypothesis.)
