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)

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.
