Roy's Texaco wants to keep the price of its unleaded gasoline competitive with that of other stations in the area. Roy's is currently charging $1.29 per gallon. To check that the average price for this gasoline for all stations within 12-mile radius is higher than his price, Roy randomly samples the price of unleaded gasoline at ten stations located in this area. He obtains the following data for the price per gallon (in dollars): 1.7, 1.5, 2.6, 2.2, 2.4, 2.3, 2.6, 3.0, 1.4, 2.3 Set up appropriate hypotheses and test them using a significant level of .01.

Thompson Photo Works purchased several new, highly sophisticated processing machines. The production department needed some guidance with respect to qualifications needed by an operator. Is age a factor? Is a person's mechanical aptitude score important? To evaluate the factors needed to estimate performance on the new processing machines, four variables were selected: x1 = Length of time an employee was in the industryx2 = Mechanical aptitude test scorex3 = Prior on-the-job ratingx4 = Age Performance on the new machine is designated y.Thirty employees were randomly selected and data were collected for each of the variables. A few results follow: Name Performance on New Machine,y Length of Time in Industry,x1 Mechanical Aptitude Score,x2 Prior On-the-Job Performance,x3 Age,x4 Mike Miraglia 112 4 392 119 41 Sue Trythall 117 5 305 127 30 The equation is:yˆy⁢^⁢ = 10.3 + 0.4x1 + 0.986x2 + 0.212x3 + 0.007x4 As age increases by one year, how much does estimated performance on…
