America Online posted this question on its Web site: “How much stock do you put in long-range weather forecasts?” Among its Web site users, 38,410 chose to respond.

a. Among the responses received, 5% answered with “a lot.” What is the actual number of responses consisting of “a lot?”

b. Among the responses received, 18,053 consisted of “very little or none.” What percentage of responses consisted of “very little or none?”

c. Because the sample size of 38,410 is so large, can we conclude that about 5% of the general population puts “a lot” of stock in long-range weather forecasts? Why or why not?
