The Pew Research Center asked a sample of Americans, “Do you know someone who has entered a long-term relationship via online dating?” The table gives the total number of people by level of educational attainment (rounded) and the percentage who said Yes.

a. Make a two-way table of counts (not percentages). The table is started below.

Suppose a person is randomly selected from this group.

b. What is the probability the person knows someone who has entered a long-term relationship via online dating?

c. If you select from the people who said Yes, what is the probability that the person has some college or is a college grad?

d. What is the probability the person said Yes and is a college grad?

e. As educational attainment increases, what is the trend in the probability that the person knows someone who has entered a long-term relationship via online dating?
