You need not enter the "*" symbol. Probability =Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 105 people in the 18-21 age bracket and finds that 89 of them respond and 16 refuse to respond. When 235 people in the 22-29 age bracket are contacted, 210 respond and 25 refuse to respond. Assume that 1 of the 340 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) = (Hint: It might be helpful to organize the data into a table first.)Assortative Mating: Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/ or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 214 Scandinavian men and their female partners. The table below summarizes the results (rows represent male eye color while columns represent female eye color). For simplicity, we only include heterosexual relationships in this exercise .
