     The owner   of a moving company would like to be able to predict the number of hours   required to complete a move by using the number of cubic feet of items moved.   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          Cubic Feet   (x) Hours (y)   545 24   400 13.5   562 26.25   540 25   220 9   344 20   569 22   340 11.25   900 50   285 12   865 38.75   831 40   344 19.5   360 18   750 28   650 27   415 21   275 15   557 25   1028 45   793 29   523 21   564 22   312 16.5   757 37   600 32   796 34   577 25   500 31   695 24   1054 40   486 27   442 18   1249 62.5   995 53.75   1397 79.5
