- 3. J.D. Power and Associates conducts vehicle quality surveys to provide automobile manufacturers with consumersatisfaction information about their products (Vehicle Quality Survey, January 2010). Using a sample of vehicleowners from recent vehicle purchase records, the survey asks the owners a variety of questions about their newvehicles, such as those shown below. For each question, state whether the data collected are categorical orquantitative and indicate the measurement scale being used.a. Did you purchase or lease the vehicle?b. What price did you pay for the vehicle?c. How likely would you be to recommend this vehicle to a friend? (Definitely Not, Probably Not, Probably Will,and Definitely Will)d. What is your overall rating of your new vehicle (Unacceptable, Average, Outstanding, or Truly Exceptional)?In order to determine whether the significant difference in the durability of 3makes of computers, samples of size 5 are selected from each make and the frequency of repair during the first year of purchase is observed. The results are as follows: In view of the above data, what conclusion can you draw?MakesA B C5 8 76 10 38 11 59 12 47 4 1Complete the table below.
