Data were collected on the number of days per week that members visit a certain fitness center. The values varied from 0 to 7, and a distribution of relative frequencies for the values was created. Let the random variable X represent the number of days per week that a member visits. The mean of X is 3.12. Which of the following statements is the best interpretation of the mean?
a. Each member visits the fitness center 3 or 4 days per week
b. The average number of days that each member visits the fitness center is 3.12 days per week.
c. Half the members visit the fitnest center 3 days per week or less, and the other half visit 4 days per week or more.
d. The long-run average resulting from repeated sampling of members of the fitness center will approach 3.12 days per week E
e. For a random sample of members selected from the population, the average number of visits for the sample will be 3.12 days per week
