Construct and interpret a residual plot

Question 1 of 8

Calculator allowed

The paired data use parcels handled as the explanatory variable and processing time as the response variable

Let \(x\) represent parcels handled and \(y\) represent processing time. The fitted model is:

\hat y = -81.9 + 4.0x

For each case, calculate the predicted response, then residual = actual response minus predicted response

The paired data and selected fitted values are shown below

Case	parcels handled (parcels)	processing time (min)	Predicted response	Signed vertical departure
Case 1	23	10.3	10.1	0.2
Case 2	24	13.2	?	?
Case 3	25	18.9	18.1	0.8
Case 4	26	21.4	22.1	-0.7
Case 5	27	26.7	26.1	0.6
Case 6	29	34.7	34.1	0.6
Case 7	30	37.4	38.1	-0.7
Case 8	31	42.9	42.1	0.8
Case 9	32	45.2	46.1	-0.9
Case 10	33	50.3	50.1	0.2
