A diet center claims that it has the most effective weight loss program in the region. Its advertisements say, "Participants in our program lose more than 5 pounds within a month." Six clients of this program are weighed on the first day of the diet and then one month later. Let the difference be defined as Weight on First Day of Diet minus Weight One Month Later.
| Client | Weight on First Day of Diet | Weight One Month Later |
| 1 | 155 | 171 |
| 2 | 186 | 190 |
| 3 | 174 | 165 |
| 4 | 201 | 182 |
| 5 | 163 | 153 |
| 6 | 157 | 130 |
Assuming that weight loss is normally distributed, calculate the value of the test statistic.

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...

An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than 10 pounds. A consumer activist decides to test the authenticity of the claim. She follows the progress of 18 women who recently joined the weight-reduction program. She calculates the mean weight loss of these participants as 10.8 pounds with a standard deviation of 2.4 pounds. Which of the following are appropriate hypotheses to test the advertisement's claim?

The weights (in pounds) of 30 participants are recorded before
and after a 6 week exercise program.
A. Calculate the difference between the before weight and after
weight of all 30 participants, where a negative value represents
losing weight. Then, find the mean difference of weights. (Round
your answer to the nearest hundredth)
B. Next, find the sample standard deviation for the difference
of weights. (Round your answer to the nearest hundredth)
