CHAPTER 9 THE BINOMIAL CASE STUDY AND GRADING RUBRIC
Student name:
Many retirement apartment communities have an emergency response team on the premises to serve
residents in need – 24 hours per day, seven days per week. A resident can make an emergency call
by pulling on any one of several wall cords located in bathrooms and other rooms in the apartment.
After pulling the cord, these teams are supposed to arrive at a resident’s apartment within three
minutes of an emergency call for help or ambulance by the resident. The community Manager has
been asking some residents who have made emergency calls “how long did it take for the emergency
response team to arrive for you?” Design a test of ten trials to determine whether the emergency
response teams either tend to arrive within 3 minutes, or tend to take later than three minutes.
Then, use 10 notional (dummy) emergency response times to demonstrate your test at the 95%
confidence level. Use these times to perform the calculations and draw a mock conclusion. Assume
that the design of your test will be tried by the community Manager if it is detailed enough.
1. Describe the test you are proposing. 3 pts.
Based on that design and a set of ten notional (dummy) numbers for demonstration purposes only,
answer the following.
2. State the null hypothesis. 1 pt.
3. State the alternative hypothesis. 1 pt.
4. State the significance level. 1 pt.
5. Perform the calculations; include the notional data. 3 pts.
6. Should the null hypothesis be accepted or rejected? Answer only one. Describe what you mean
by “accepted” or “rejected.” 3 pts.
Yes, because:
or
No, because:
