19.12 In Chapter 1, Table 1.1 lists the weights of 53 male statistics students. Although students were asked to report their weights to the nearest pound, inspection of Table 1.1 reveals that a disproportionately large number (27) reported weights end- ing in either a 0 or a 5. This suggests that many students probably reported their weights rounded to the nearest 5 or 10 pounds rather than to the nearest pound. Using the .05 level of significance, test the null...

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. (Some people call...

The weight of male students at a certain university is normally distributed with a mean of 175 pounds with a standard deviation of 7.6 pounds. Find the probabilities. 1. A male student weighs at most 186 pounds. 2. A male students weighs at least 160 pounds. 3. A male student weighs between 165 and 180 pounds. Please show work. Ideally excel commands would be helpful, but anything would be great!

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)

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...
