- 1.Moving times (in minutes) and weights (in pounds) were recorded for a random sample of 20 moving jobs requiring three-man crews, and the results of the regression analysis are shown below. The equation for the least-squares regression line is:
- A.
Predicted weight = 21.84 + 0.037(Time)
- B.
Predicted time = 21.84 + 0.037(Weight)
- C.
Predicted weight = 25.54 + 0.003(Time)
- D.
Predicted time = 25.54 + 0.003(Weight)
- E.
Predicted time = 0.037 + 21.84(Weight)
- 2.The cause of death and the age of the deceased are recorded for 454 patients from a hospital. Use these values to estimate the probability that a person at this hospital died as a result of an accident if it is known the person was between the ages of 45 and 54.
- A.
0.0264
- B.
0.0976
- C.
0.1322
- D.
0.2000
- E.
0.4878
- 3.The median of a distribution is 150, and the interquartile range is 50. Identify the statement(s) that must be true. (I). Apprx. 50% of the data are between 125 and 175. (II). Apprx. 50% of the data are less than or equal to 150. (III). Apprx. 75% of the data are greater than 125.
- A.
I only
- B.
II only
- C.
I and III only
- D.
II and III only
- E.
I, II, and III
- 4.For Hospital A, the average waiting time (time between walking in the door and seeing a doctor) in the emergency room is 135 minutes with a standard deviation of 45 minutes. For Hospital B, the average waiting time in the emergency room is 90 minutes with a standard deviation of 22.5 minutes. In which hospital are you more likely to wait less than 45 minutes? Assume the distribution of waiting times are normal.
- A.
Hospital B, because the average wait-time is only 90 minutes, rather than 135 minutes in Hospital A.
- B.
Hospital A, because with twice the standard deviation of Hospital B, it has twice the spread.
- C.
Neither, because for both hospitals, the probability of waiting less than 45 minutes is 2.275%.
- D.
Neither, because for both hospitals, the probability of waiting less than 45 minutes is 97.725%.
- E.
It is impossible for any patient to wait less than 45 minutes in either hospital unless the patient is in critical condition.
- 5.A regression equation is given as log(y-hat) = 0.214 - 1.28(x). What is the (approximate) predicted value for y when x = 2?
- A.
- 2.346
- B.
- 0.171
- C.
0.005
- D.
0.167
- E.
Cannot be determined.
