He has collected data for 36 moves in which the origin and destination were within the city limits of Coral Gables and in which the travel time was an insignificant portion of the hours worked. Q-1a: What is the slope of the least squares regression line? (Round to four decimals.) Q-1b: What is the y-intercept of the least squares regression line? (Round to four decimals.) Q-1c: Predict the number of hours required to complete a move involving 920 cubic feet of items moved. (Round to one decimal place.) Summarize your findings
