One hundred Canadians have been classified into groups ?, ?, and ? based on age, with 45 people in group ?, 25 in group ?, and 30 in group ?. It is known that 20 people in group ? have been vaccinated against a certain virus, while 10 people in group ? and 20 in group ? have been. If a person is randomly chosen from the 100 Canadians and it turns out they are someone who was not vaccinated,...

In order to qualify for a job opening, applicants must have a some experience in statistics. 45 individuals submit an application for the job, of which only 10 individuals actually have experience with statistics. Suppose that 5 applicants are randomly selected to be interviewed on the first day, with the remaining applicants to be interviewed later in the week (we can assume that once an individual has been selected to be interviewed, he or she will not be selected again)....

In a region, 80% of the population have brown eyes. If 15 people are randomly selected, find the probability that at least 13 of them have brown eyes. Is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? Why or why not? The probability that at least 13 of the 15 people selected have brown eyes is (Round to three decimal places as needed.)

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 80 people in the 18-21 age bracket and finds that 68 of them respond and 12 refuse to respond. When 265 people in the 22-29 age bracket are contacted, 241 respond and 24 refuse to respond. Assume that 1 of the 345 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respond. Give...
