# Question

A Gallup poll asked, “Do you think that rich people in America today are happier than you, less happy, or about the same?” In 1990, 36% said less happy, 11% said hap-pier, and 50% said about the same. The reason these don’t add up to 100% is that there were some people who had no opinion. Suppose Gallup were to do another survey polling 1500 people, and the percentages were the same as those in 1990.

a. How many would say less happy?

b. How many would say happier?

c. How many would say about the same?

a. How many would say less happy?

b. How many would say happier?

c. How many would say about the same?
