The paired measurements compare parcels handled with processing time

Scatterplot with 6 plotted pairs. The horizontal axis is parcels handled (parcels) and the vertical axis is processing time (min). The plotted values for parcels handled run from 55 to 67, and the plotted values for processing time run from 111 to 139. The plotted pairs are (55, 116), (57, 111), (59, 121), (63, 126), (65, 139), (67, 137).

(a)1 mark

For this estimate, use the fitted line through (59, 121) and (63, 129). Read an estimate of the response value from the drawn line. The given parcels handled is 58 parcels. Round your estimate to a whole number of the displayed units
