In a recent survey of full-time female workers ages 22 to 35 years, 46% said that they would rather give up some of their salary for more personal time. (Data extracted from "I'd Rather Give Up,"USA Today, March 4, 2010, p. 1B.) Suppose you select a sample of 100 full-time female work- ers 22 to 35 years old.
What is the probability that in the sample, fewer than 50% would rather give up some of their salary for more personal time?
What is the probability that in the sample, between 40% and 50% would rather give up some of their salary for more personal time?
What is the probability that in the sample, more than 40% would rather give up some of their salary for more personal time?
If a sample of 400 is taken, how does this change your answers to (a) through (c)?
