Deepa Dalal opened a free-standing radiology clinic. She had anticipated that the costs for the radiological tests would be primarily fixed, but she found that costs increased with the number of tests performed. Costs for this service over the past nine months are as follows: Total Cost Month Radiology Tests 2,800 2,600 3,100 3,500 3,400 3,700 3,840 4,100 3,450 $133,500 135,060 175,000 170,600 176,900 186,600 174,450 195,510 185,300 January February March April May June July August September What does the coefficient of determination tell you about the cost formula computed in Requirement 1? What are the t statistics for the number of tests and the intercept term? What do these statistics tell you about the choice of number of tests as the independent vari- able and the probability that there are fixed costs? 3
