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?

Your Algebra 2 teacher collected data on the number of days each student was
absent during a semester and their score, in percent, on the semester exam.
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.

- QUESTION 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?

- Question 8 Central Perk orders their organic coffee filters from a South American supplier that mails them as inexpensively (hence, as slowly) as possible. Central Perk uses 80 filters a day with a standard deviation of 5 filters per day. It would be disastrous if they ran out of these filters, years ago customers caught them using paper towels from the men's room and business suffered. They have set their service level at 99% in hopes of avoiding a similar situation. It takes 14 days to receive a shipment and the standard deviation of the shipping time is two days.

The recommended dosage for the flu shot is 0.5mL. The local health authorities define all syringes that have less than 0.45ml or more than 0.55mL as defective. In a sample of 100 syringes, the hospital’s quality control officer finds the average dosage to be 0.5mL. The standard deviation of the dosage is 0.02 mL and the distribution of the dosages resembles a normal distribution reasonably closely. What percentage of the manually filled syringes will be outside the specification limits provided by the local health authorities? (Please answer in decimal form.)arrow_forward
