For 45 cities in the U.S, we found a correlation of 0.86 between internet use and online shopping. The regression equation predicting online shopping is ŷ =15+ 0.8 *Internet use a. Based on the correlation value, is the slope positive or negative? Why? b. Honolulu had an internet use of 91% and online shopping of 85%. Find its predicted online shopping based on the regression equation. c. Find the residual for Honolulu. Interpret the result

4) The regression equation predicting the average weight of a male age 18=24 (y) based on his height (x) is giben by y= 172.63+4.842x. Describe the correlation between height and weight based on the slop of the regression line. a) positive correlation since the magnitude of the slope is large relative to the intercept. b) negative correlation since the magnitude of the slope is small relative to the intercept. c) positive correlation since the slope is positive. d) positive correlation...

Colleges use SAT scores to predict how students will perform at the college level. Suppose the entering freshmen at a certain college have mean SAT Scores of 1200, with a standard deviation of 113. In the first semester these students attained a mean GPA of 2.57, with a standard deviation of 0.46. A scatterplot showed the association to be reasonably linear, and the correlation between SAT score and GPA was 0.39. a) Write the equation of the regression line. b)...

The OECD (Organization for Economic Cooperation and Development) consists of 20 advanced, industrialized countries. Based on these 20 cases, the regression equation relating X = percent of gross domestic product devoted to social expenditure and Y = child poverty rate is E(Y) = 22 – 1.3X. The values of X range from 2% (United States) to 16% (Denmark). The values of Y range from 2.8% (Finland) to 21.9% (United States). The correlation between X and Y is –0.79. Interpret the...
