The average age of residents in a large residential retirement community is 69 years with standard deviation 5.8 year A simple random sample of 100 residents is to be selected, and the sample mean age of these residents is to be computed. We know the random variable has approximately a Normal distribution because: O a. of the central limit theorem b. of the law of large numbers. c. of the 68% 95% 99.7% rule. O d. the population from which we're sampling has a Normal distribution.
