Textbook Question
Chapter 3, Problem 75CP
College GPA = high school GPA Refer to the previous exercise. Suppose the regression equation is yn = x. Identify the y-intercept and slope. Interpret the line in context.
3.74 Predicting college GPA An admissions officer claims that at his college the regression equation yn = 0.5 + 7x approximates the relationship between y = college GPA and x = high school GPA, both measured on a fourpoint scale.
- a. Sketch this equation between x = 0 and 4, labeling the x- and y-axes. Is this equation realistic? Why or why not
- b. Suppose that actually yn = 0.5 + 0.7x. Predict the GPA for two students having GPAs of 3.0 and 4.0. Interpret and explain how the difference betweenthese two predictions relates to the slope.

- iid 1. The CLT provides an approximate sampling distribution for the arithmetic average Ỹ of a random sample Y₁, . . ., Yn f(y). The parameters of the approximate sampling distribution depend on the mean and variance of the underlying random variables (i.e., the population mean and variance).
