The ages (in years) of 10 infants and the numbers of hours each slept in a day

(a) x = 0.3 year

(b) x = 3.9 years

(c) x = 0.6 year

(d) x = 0.8 year

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.
