In a survey, a statistician analyzed the relationship between the Mothers-Heights (explanatory vari-
able x) and the Daughters-Heights (response y) by using the regression method. When he drew the
regression line, he found that at x = 0 the predicted response is yı = 29.9, and at x2 = 1 the pre-
dicted response is y2 = 30.43. Suppose that the standard deviations of Daughters-Heights is S, = 2.6
and Mothers-Heights is Sc = 2.35.
Please answer the following questions underneath each question.
