For Exercises use the same data as for the corresponding exercises in Section 10–1. For each exercise, find the equation of the regression line and find the y  value for the specified x value. Remember that no regression should be done when r is not significant.

Stories and heights of buildings data follow:

Find ý when x = 44.

An architect wants to determine the relationship between the heights (in feet) of a building and the number of stories in the building. The data for a sample of 10 buildings in Pittsburgh are shown. Explain the relationship.
