Problem 5RE

In Exercises , refer to the table in the margin. The random variable x is the number of males with tinnitus (ringing ears) among four randomly selected males (based on data from “Prevalence and Characteristics of Tinnitus among US Adults” by Shargorodsky et al,American Journal of Medicine, Vol. 123, No. 8).

Tinnitus Does the table describe a probability distribution? Why or why not?

Step-by-Step Solution:

Step 1 of 1

Yes, three is an unusually high number of males with tinnitus among four randomly selected males.

The three requirements are satisfied.

There is a numerical random variable x and its values are associated with corresponding probabilities.

∑ P ( x ) = 1.001 ,  so the sum of the probabilities is 1 when we allow for a small discrepancy due to rounding. Also, each of the probability values is between 0 and 1 inclusive.
