You are the manager of a removal company and want to develop a more accurate way of predicting the labour requirements for moving jobs. You decide to use the volume of goods (in cubic metres) that is being moved. You have the following data from the last 10 moves. Calculate the regression model for predicting the number of hours needed based on the volume of goods to be moved. Does the prediction seem plausible?

Hours ................... Cubic metres of goods moved
18 .......................................... 60
14 .......................................... 40
27 .......................................... 90
9 ............................................ 20
22 .......................................... 70
15 .......................................... 34
18 .......................................... 56
15 .......................................... 42
4 ............................................ 10
14 .......................................... 39
