Operations managers often use work sampling to estimate how much time workers spend on each operation. Work sampling—which involves observing workers at random points in time—was applied to the staff of the catalog sales department of a clothing manufacturer. The department applied regression to the following data collected for 40 consecutive working days:

TIME:  y = Time spent (in hours) taking telephone orders during the day

ORDERS: x1 = Number of telephone orders received during the day

WEEK: x2 = 1 weekday, 0 if Saturday or Sunday

Consider the complete 2nd-order model:

E(y) = β0 + β1x1 + β2(x1)2 + β3x2 + β4x1x2 + β5(x1)2x2

Explain how to conduct a test to determine if a quadratic relationship between total order time and the number of orders taken is necessary in the regression model above. Specify the null and alternative hypotheses that are to be tested.
