Question

The American Heart Association reported that, for people 18 years of age or older in the United States, an estimated 24.8 million men (23.1%) and 21.1 million women (18.3%) are cigarette smokers. Find the probability that a randomly selected person 18 years of age or older in the United States is a cigarette smoker. Write the answer as a decimal, rounded to the nearest thousandth. Assume one half of the population is male.

Answer #1

The Centers for Disease Control reported the percentage
of people 18 years of age and older who smoke (CDC website,
December 14, 2014). Suppose that a study designed to collect new
data on smokers and nonsmokers uses a preliminary estimate of the
proportion who smoke of .25.
a. How large a sample should be taken to estimate the proportion
of smokers in the population with a margin of error of .02 (rounded
up to the next whole number)? Use 95%...
