She randomly selects 11 children from her practice, measures their heights and head circumferences, and obtains the accompanying data. Height Head inches), Circumference (inches), y 27.5 17.7 24.5 17.3 25.5 17.3 25.75 17.7 24.25 17.0 28 17.8 26.25 17.5 27.25 17.7 26.5 17.5 26.5 17.7 28 17,7 (a) Find the least-squares regression line treating height as the explanatory variable and head circumference as the response variable. Say briefly how you used the calculator to find this. (b) Interpret the slope and y-intercept, if appropriate. Give the value of each and a sentence saying what it means in the context of this problem. (c) Use the regression equation to predict the head circumference of a child who is 25.75 inches tall. Show how you found that value. (d) Would it be reasonable to use the least-squares regression line to predict the head circumference of a child who was 32 inches tall? Why
