The study of investigators conjectured that there would be an increase in weight but that the rate of increase would level off toward the end of the study. They also conjectured that this pattern of change may differ in the three treatment groups. Assuming an unstructured covariance matrix, construct a test for this hypothesis.

i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
