Question 12 (1 point)
Suppose that a researcher studying the weight of female college
athletes wants to predict the weights based on height, measured in
inches, the percentage of body fat of an athlete, and age. The
researcher calculates the regression equation as (weight) =
3.551*(height) + 0.558*(percent body fat) - 1.153*(age) - 91.16. If
a female athlete is 61 inches tall, has a 20 percentage of body
fat, is 23 years old, and has a weight of 226.326, the...

One sample t-test : A new weight-reducing pill is being sold in
a Midwestern town. The manufacturer claims that any overweight
person who takes this pill as directed will lose 15 pounds within a
month. To test this claim, a doctor gives this pill to 6 overweight
people and finds that they lose an average of only 12 pounds with a
standard deviation of 4 pounds. Can we reject the manufacturer’s
claim? (Use a 5% level of significance).

Question 10 (1 point)
Suppose that a researcher studying the weight of female college
athletes wants to predict the weights based on height, measured in
inches, and the percentage of body fat of an athlete. The
researcher calculates the regression equation as (weight) =
4.761*(height) + 0.92*(percent body fat) - 90.224. If a female
athlete is 63 inches tall and has a 18 percentage of body fat, what
is her expected weight?

1. If we increase our food intake, we generally gain weight.
Nutrition scientists can calculate the amount of weight gain that
would be associated with a given increase in calories. In one
study, 16 nonobese adults, aged 25 to 36 years, were fed 1000
calories per day in excess of the calories needed to maintain a
stable body weight. The subjects maintained this diet for eight
weeks, so they consumed a total of 56,000 extra calories. According
to theory, 3500...
