Explanation / Answer

29. Using Excel Command =intercept(x, y)

We get approximately the value of intercept is 0.

31. Using Excel Command =slope(x, Y)

We get value of slope is 2.

So therefore the regression equation is y=0+2*x

So therefore, approximate predicted time for 6 jobs is

y=2*6=12.

32

d. 6 in the numerator and 6 in the denominator.
