QUESTION 3
In an effort to reduce energy costs, a major university has installed more efficient lights as well as automatic sensors that turn the lights off when no movement is present in a room. Historically, the cost of lighting an average classroom for 1 week has been $265. To determine whether the changes have signficantly reduced costs, the university takes a sample of 50 classrooms. They find that the average cost for 1 week is $247 with a standard deviation of $60. When testing whether the average energy use has decreased from the past (with a null hypothesis that the use has increased) (using the 5% level of significance), what is the p-value? (please round your answer to 4 decimal places)
Question 2:
Sunblessed Juice Company sells bags of oranges and cartons of orange juice. Sunblessed grades oranges on a scale of 1 (poor) to 10 (excellent). At present, Sunblessed has 220,000 pounds of grade 6 oranges and 150,000 pounds of grade 9 oranges on hand. The average quality of oranges sold in bags must be at least 7, and the average quality of oranges used to produce orange juice must be at least 8. Each pound of oranges that is used for juice yields a revenue of $2.25 and incurs a variable cost (consisting of labor costs, variable overhead costs, inventory costs and so on) of $1.35. Each pound of oranges sold in bags yields a revenue of $2.00 and incurs a variable cost of $1.20.
Determine how Sunblessed can maximize its profit. Please include your answer report with the model, and a description of your recommendation.
Use SolverTable to determine how a change in the cost per bag of oranges changes the optimal solution. Specifically, vary the cost from $1.00 to $1.50 in…
