Question

A company has observed that there is a linear relationship between indirect labor expense (ILE) , in dollars, and direct labor hours (DLH). Data for direct labor hours and indirect labor expense for 18 months are given in the file ILE_and_DLH.xlsx

(this is the ILE a nd DLH File below )

DLH(X)	ILE(Y)
20	361
25	400
22	376
23	384
20	361
19	360
24	427.2
28	458.4
26	450.8
29	475.2
27	462.6
25	445
28	511
32	550.8
35	587.8
34	574.1
30	535.4
36	591.5

Treating ILE as the response variable, use regression to fit a straight line to all 18 data points. What values for the intercept (a)  and slope (b) do you obtain?

Place your answers, rounded to 3 decimal places, in the blanks provided. Do not use any stray punctuation marks. For example, 34.567 would be a legitimate entry.

intercept (a) =
slope(b) =
