The following data is looking at how long it takes to get to work. let x = commuting distance (miles) and y = commuting time (minutes) x 15 16 17 18 19 20 y 42 35 45 42 49 46
a. give a scatterplot of this data and comment on the direction, form and strength of this relationship. b. determine the least-squares estimate equation for this data set. c. give the r2, comment on what that means. d. give the residual plot based on the least-squares estimate equation. e. test if this least-squares estimate equation specify a useful relationship between commuting distance and commuting time.
