Suppose I’m comparing the times that doctors have with patients at two different hospitals. At Hospital A, the mean is 17 minutes, and the standard deviation is 10 minutes. At Hospital B, the mean is 24 minutes, and the standard deviation is 2 minutes. Answer the following:(a) Which is longer, 4 minutes with the doctor at Hospital A or 4 minutes with the doctor at Hospital B? Why? (b) Suppose you only care about how much time you get with the doctor and no other factors. Which hospital would you rather visit and why? Note, there’s a case to be made for either hospital, so be sure to focus on the “why” part of your answer.

Suppose I’m comparing the times that doctors have with patients at two different hospitals. At Hospital A, the mean is 17 minutes, and the standard deviation is 10 minutes. At Hospital B, the mean is 24 minutes, and the standard deviation is 2 minutes. Answer the following:

(a) Which is longer, 4 minutes with the doctor at Hospital A or 4 minutes with the doctor at Hospital B? Why?

(b) Suppose you only care about how much time you get with the doctor and no other factors. Which hospital would you rather visit and why? Note, there’s a case to be made for either hospital, so be sure to focus on the “why” part of your answer.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
