28. Eating on the Run How do you survive when there’s no time to eat—fast food, no food, a protein bar, candy? A USA Today snapshot indicates that 36%

of women aged 25–55 say that, when they are too busy to eat, they get fast food from a drive-thru. A random sample of 100 women aged 25–55 is selected.

a. What is the average number of women who say they eat fast food when they’re too busy to eat?

b. What is the standard deviation for the number of women who say they eat fast food when they’re too busy to eat?

c. If 49 of the women in the sample said they eat fast food when they’re too busy to eat, would this be an unusual occurrence? Explain.
