Suppose that a random sample of 200 twenty-year-old men is selected from a population and that these men's height and weight are recorded. A regression of weight on height yields

Weight = ( -105.3746) + 4.1764 x Height, R² = 0.86, SER 10.8

Weight is measured in pounds and Height is measured in inches.

The regression's weight prediction for someone who is 75 inches tall is _____ pounds. (Round your response to two decimal places.)

A man has a late growth spurt and grows 1.3 inches over the course of a year. What is the regression's prediction for the increase in this man's weight?

The regression's prediction for the increase in this man's weight is ________ pounds. (Round your response to two decimal places.)

Suppose that instead of measuring weight and height in pounds and inches these variables are measured in centimeters and kilograms (1 in = 2.54 cm and 1 lb = 0.4536

kg).

Suppose the regression equation in centimeter-kilogram units is:

Weight = ₀+₁ Height

The regression estimates from this new centimeter-kilogram regression are:

₀ = _______ kg. (Round your response to four decimal places.)

₁ = ________ kg per cm. (Round your response to four decimal places.)

R² = ________ (Round your response to two decimal places.)

SER = __________ kg. (Round your response to four decimal places.)
