Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 90 people in the 18-21 age bracket and finds that 76 of them respond and 14 refuse to respond. Whe 254 people in the 22-29 age bracket are contacted, 232 respond and 22 refuse to respond. Assume that 1 of the 344 people is randomly selected. Find the probability of getting someone in the 18-21 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(18-21 or refused) = %3D (Hint: It might be helpful to organize the data into a table first.) Question Help: e Written Example Message instructor
