Question

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 83 people in the 18-21 age bracket and finds that 70 of them respond and 13 refuse to respond. When 277 people in the 22-29 age bracket are contacted, 262 respond and 15 refuse to respond. Assume that 1 of the 360 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or refused) = % (Hint: It might be helpful to organize the data into a table first.)
