Sir Francis Galton, in the late 1800s, was the first to introduce the statistical concepts of regression and correlation. He studied the relationships between pairsof variables such as the size of parents and the size of their offspring.Data similar to that which he studied are given below, with the variable x denoting the height (in centimeters) of a human father and the variable y denoting theheight at maturity (in centimeters) of the father's oldest son. The data are given in tabular form and also displayed in the Figure 1 scatter plot. Also given is theproduct of the father's height and the son's height for each of the fifteen pairs. (These products, written in the column labelled "xy", may aid in calculations.)Height offather, x(incentimeters)176.6181.3171.6158.3181.5190.5161.2191.2175.9Height of son,y(incentimeters)173.4188.9180.7175.0176.3189.2168.5194.8179.5191.3171.2200.0170.1192.2162.0186.8184.9Send data to calculator190.9172.1176.4186.8xy30,622.4434,247.5731,008.1227,702.531,998.4536,042.627,162.237,245.7631,574.0538,26029,121.1236,690.9827,880.232,951.5234,539.32Height of son(in centimeters)Figure 1210+200+190+180-170+160-150+150160X170 180 190 200Height of father(in centimeters)210What is the slope of the least-squares regression line for these data?

The value of a sports franchise is directly related to the amount of revenue that a franchise can generate. The accompanying data table gives the value and the annual revenue for 15 major sport teams. Suppose you want to develop a simple linear regression model to predict franchise value based on annual revenue generated. b. Assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1. (Round the value of b0 to the nearest integer as needed. Round the value of b1 to two decimal places as needed.)
