Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 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 359 people is randomly splected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respornd. Report the answer as a percent rounded to one decimal place accuracy.

There are declining levels of cooperation among persons contacted in surveys and this brings concerns to pollsters. A pollster contacts 92 people in the 18-21 age bracket and finds that 78 of them respond and 14 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 259 respond and 17 refuse to respond. Assume that 1 of the 368 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond. Report the answer as a percent rounded to one decimal place accuracy.

A gender-selection technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique, 962 births consisted of 490 baby girls and 472 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 490 girls in 962 births. b. Find the probability of getting 490 or more girls in 962 births. If boys and girls are equally likely, is 490 girls in 962 births unusually high?
From experience, the human resources director of a certain company estimates that, for a particular job opening, 80% of the applicants are qualified. To help in the selection process, a test has been designed so that a qualified applicant has an 85% chance of passing the test, while an unqualified applicant has only a 5% chance of passing. An applicant is selected at random. a. What is the probability that the applicant is qualified and will pass the test? b. If the applicant passed the test, what is the probability that he or she is unqualified for the job?
In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household) Among the respondents, 208 answered "none", 285 said "one", 358 said "two", 149 said "three", and 129 responded with four or more. A survey respondent is selected at random. Find the Probability that his/her household has four or more cell phones in use. Is it likely for a household to have four or more cell phones in use? Consider and event to be unlikely if its probability is less than or equal to 0.05.
