Please answer the below question.
Suppose that we are interested in predicting weight of students based on height. We have run a regression analysis with the resulting estimated regression equation as follows: "The estimated weight equals (−180 pounds) plus (5 pounds times the height in inches)."
- Suppose that one student is 3 inches taller than another student. What is the estimated difference in weight?
- Suppose that a given student is 65 inches tall. What is the estimated weight?
- Explain clearly the meaning of the 5 in the equation above.
- Explain clearly the meaning of the −180 in the equation above.

2. Suppose we wanted to compare the heights of two students: Joe, a 69-inch-tall student in this class (where y = 65.5 inches and = 3.06 inches), and Michael, a 65-inch-tall student in a different class (where y=64.0 inches and 2.75 inches). Show your work to determine which student is taller, compared to his peers, and explain how you came to your conclusion.

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) 4.358 (height) 0.713 (percent body fat)-85.095. If a female athlete is 65 inches tall, has a 16 percentage of body fat, and a weight of 210.005. What is the residual? 1) -84.673 2) 0.422 3) We do...
