Part B- Short Answer Problems 1) Johnson Filtration, Inc. provides maintenance service for water-filtration systems. To better estimate repairs times for improved scheduling, the company collected data that show the repair time in hours, the months since last service ('Months'), the repair type (either electrical or mechanical) and the repair person (denoted as simply "technician 1" and "technician 2") for a sample of 40 recent maintenance service calls. As both repair type and repair person are categorical variables, both were...

Johnson Filtration, Inc., provides maintenance service for water fitration systems throughout southern Florida. Customers contact Johnson with requests for maintenance service on their water filtration systems. To estimate the service time and the service cost Johnson's manacers want to predict the repair time necessary or each maintenance request. Hence, repair time in hours is the dependent variable. Repair tme is believed to be related to three factors; the number of months snce the as maintenance service, the type of repair...

This preamble applied to questions 1 & 2 (Based loosely on textbook page 442) Say we are interested in examining the linear relationship between the monthly labour hours required in a hospital (y), the monthly x-ray exposures (x1), monthly occupied bed days (x2), and average length of stay (x3). We gather 10 observations, and input the data into Excel. We obtain the following output Intercept X Variable 1 X Variable 2 X Variable 3 Coefficients 1134.56 0.16 0.27 -147.93 Standard...

Logout This preamble applies to all the remaining questions. The questions are based on the lecture example for regression with categorical data. In the lecture example, we were analyzing the association of Repair time (y), the dependent variable, with the Time since last service (X1), and the Repair type (x2). Where x2 was a dummy variable coded 1 for an electrical repair and 0 for a mechanical repair. This time we inversely coded x2 ; i.e. x2 = 1 if...
