According to a recent survey, 47.9 percent of housing units in a large city are rentals. A sample of 210 housing units will be r
andomly selected. Which of the following must be true for the sampling distribution of the sample proportion of housing units in the large city that are rentals to be approximately normal?
According to the central limit theorem the sample size must be greater than 30 in sampling distributions to state that it is approximately normal.
Therefore, the sample size must be greater than 30 for the sampling distribution of the sample proportion of housing units in the large city that are rentals to be approximately normal.
