5. The following data give the highest daytime temperature ◦F and amount of rainfall

(in inches) on 10 randomly selected summer days at a tourist place in the northeastern United States:

Temperature, X: 91 90 96 94 87 90 93 81 94 91 Rain, Y: 0.8 0.4 0.5 0.7 0.3 0.4 0.6 0.1 0.4 0.7 15.2 Fitting the Simple Linear Regression Model 635

(a) Construct a scatter plot for these data. Does the scatter plot indicate a straight-line would provide a good fit?

(b) Fit a regression line to these data for predicting the amount of rainfall.

(c) Using (b), record the least-squares estimates of the regression coefficient.
