Question
• F.5 Arnold Palmer Hospital is studying the number of emergency surgery kits that it uses on weekends. Over the past 40 weekends, the number of kits used was as follows:
| NUMBER OF KITS | FREQUENCY |
| 4 | 4 |
| 5 | 6 |
| 6 | 10 |
| 7 | 12 |
| 8 | 8 |
The following random numbers have been generated: 11, 52, 59, 22, 03, 03, 50, 86, 85, 15, 32, 47. Simulate 12 weekends of emergency kit usage. What is the average number of kits used during these 12 weekends?

Question 2
Mr. Ferdinand is a well known entrepreneur who sells fresh organic beef to persons in the local
community. Customers love the quality of meet that Mr. Ferdinand sells so they tend to
recommend his product to other persons. Recently, Mr. Ferdinand has been rumning out of beef
to sell to his customers. One customer suggests to him that he must use past sales records to
forecast demand for his beef so that he can meet his customers demand.
Using a numerical example, demonstrate to Mr. Ferdinand how he can use a three-
week and a four-week weighted moving average to forecast demand for his beef.
I.
II.
Show how Mr. Ferdinand can test the accuracy of his forecast.
III.
Explain to Mr. Ferdinand two ways in which he can benefit from doing forecast for
his beef.

The linear regression equation that models the data is ŷ=97.769-3.828x where x represents the number of days absent and y represents the exam score, in percent. The correlation coefficient is r=-0.707 and the coefficient of determination is =0.500. What are the appropriate interpretations of the slope, y-intercept, correlation coefficient, and coefficient of determination? **HINT** Slope: -3.828 y-intercept: 97.769 Correlation coefficient: r = -0.707 The rate the predicted semester exam score decreases for every stu- dent absence. The predicted % score a student will achieve based on having zero absences in a semester. a. correlation coefficient b. y-intercept c. slope The relationship be- tween the number of days a student was ab- sent and their corre- sponding exam score.arrow_forwardQUESTION 4 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 the hypothesis (at the 5% level of significance) that the average energy use has decreased from the past, what is your conclusion concerning the null hypothesis?
