Question: Refer to Exercises I and II. Find the height such that about 10% of college women are taller than that height. What is the percentile ranking for that height?
Exercises II: Refer to Exercise I. Find the height such that about 25% of college women are shorter than that height. What is the percentile ranking for that height?
Exercise I: Heights for college women are normally distributed with mean = 65 inches and standard deviation = 2.7 inches. Find the proportion of college women whose heights fall into the following ranges:

b. Between 60 inches and 70 inches.
c. Less than 70 inches.
d. Greater than 60 inches.
e. Either less than 60 inches or greater than 70 inches.

The regression models that we introduced in Sections 2 and 6 are linear in the x's, but, more important, they are also linear in the β's. Indeed, they can be used in some problems where the relationship between the x's and y is not linear. For in..
