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)

A manufacturer of home products is designing a new wall mount for large flat-panel televisions. Since some flat-panel televisions weigh up to 100 pounds, the manufacturer wants to make sure that the mean weight of failure for the wall mounts is greater than 180 pounds. Dayton is a researcher for the manufacturer who is conducting the test. He randomly selects 35 wall mounts and tests them by using a machine that pulls down on the mounts until each one fails....

The mean weight of U.S. men of age 30–39 years old is 191.802 pounds. Using the provided sample data file, conduct a one-sample ?-test of a mean to test whether the mean weight of men of age 30–39 years old who smoke daily is lower than 191.802. Calculate the sample mean, x¯, for this data. Give your answer precise to at least one decimal place: Compute the standard deviation, SD, of the sampling distribution of the mean.

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...
