In 1902, a statistician published the small data set consisting of the heights (in inches) of 11 adult pairs of siblings, provided below. You can also see the data set here in Statcrunch. In what follows, we will treat the brother's height as the explanatory variable and the sister's height as the response variable (although this is an arbitrary choice). a. [1 point] Determine the mean and median female height for the sisters in this survey. b. [1 point] Determine the correlation coefficient. c. [2 points] Find the least-squares regression line for predicting sister's height from brother's height. Explicitly state what you are doing to calculate this. d. [2 points] Suppose Elliot is 70 inches tall. Use your result from part c to predict his sister Tessa's height. e. [2 points] Do you expect your prediction to be very accurate? Explain.<\/p>
