Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful.

Two U.S. adults are selected from this sample without replacement. Complete parts (a) through (c). . . . (a) Find the probability that both adults think most celebrities are good role models. The probability that both adults think most celebrities are good role models is (Round to three decimal places as needed.) (b) Find the probability that neither adult thinks most celebrities are good role models. '3 ) The probability that neither adult thinks most celebrities are good role models is (Round to three decimal places as needed.) (c) Find the probability that at least one of the two adults thinks most celebrities are good role models. The probability that at least one of the two adults thinks most celebrities are good role models is (Round to three decimal places as needed.)The table below shows the results of a survey that asked 2874 people whether they are involved in any type of charity work.
