The ages (in years) and the numbers of hours of sleep in one night for seven adults

(a) x = 16 years

(b) x = 25 years

(c) x = 85 years

(d) x = 50 years

Find the equation of the regression line for the data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. If convenient, use technology.
