A simple random sample of 1200 adult Americans is selected, and each person is asked the following question: “In light of the huge national deficit, should the government at this time spend ad- ditional money to establish a national system of health insurance?” Only 39% of those responding answered “Yes.” This survey
(a)   is reasonably accurate since it used a large simple random sample.
(b)   needs to be larger since only about 24 people were drawn from each state.
(c)   probably understates the percent of people who favor a system of national health insurance.

(d)   is very inaccurate but neither understates nor over- states the percent of people who favor a system of national health insurance. Because simple random sampling was used, it is unbiased.
(e)   probably overstates the percent of people who favor a system of national health insurance.
