23. Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 97 people in the 18-21 age bracket and finds that 82 of them respond and 15 refuse to respond. When 246 people in the 22-29 age bracket are contacted, 217 respond and 29 refuse to respond. Assume that 1 of the 343 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who does not respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or does not respond) = % (Hint: It might be helpful to organize the data into a table first.)
