The Party of Nonvoters From past elections, nonvoters are those who are either not registered to vote or are considered unlikely to vote in an upcoming election. Nonvoters are very different demographically from likely voters.Nonvoters are more racially and ethnically diverse. 43% of those who are not likely to cast a ballot are Hispanic, African or other racial and ethnic minorities, roughly double the percentage amoung likely voters(22%) (Source: Pew Research Center, October, 2014, "The Party of Nonvoters"). Suppose you interview 10 people who are considered nonvoters. Round answers to 4 decimal places.a.) What is the probability that 5 of them are an ethnic minority? b.) What is the probability that more than 8 are an ethnic minority? c.) What is the probability that at least 8 are not an ethnic minority? d.) What is the probability that fewer than 5 are not an ethnic minority?

A local company is interested in supporting environmentally friendly initiatives such as carpooling among employees. The company surveyed all of the 200 employees at the downtown offices. Employees responded as to whether or not they own a car and to the location of the home where they live. The results are shown in the table below. If the person owns a car, he or she is more likely to live elsewhere in the city than to live in the downtown area in the city. If the person does not own a car, he or she is more likely to live outside the city than to live in the city (downtown area or elsewhere). The person is more likely to own a car if he or she lives in the city (downtown area or elsewhere) than if he or she lives outside the city. The person is more likely to live in the downtown area in the city than elsewhere in the city. The person is more likely to own a car than not to own a car.
The Las Vegas Review-Journal (R-J) posts an article on their website reporting on a poll they conducted for the upcoming Senate election. Their poll asked likely Nevada voters who they intend to vote for. The results were: Catherine Cortez Masto with 45%, Adam Laxalt with 41%, 14% undecided, and they report that their poll has a +/- 3.5 percentage point margin of error. The article's headline is "Cortez-Masto Leads Laxalt by 4 Points." Is the R-J right? That is, can we be reasonably sure (95% confident) that Cortez-Masto really is ahead of Laxalt? if we had the raw data we could just load it into R and do a quick difference of means test, but we don't need the actual data to figure it out in this case. In your answer, address the following: (1) Is the R-J probably right that Cortez-Masto leads Laxalt? (2) how you came to that conclusion?

Undergraduate students at Miami University in Oxford, Ohio, were surveyed in order to evaluate the effect of gender and price on purchasing a pizza fromPizza Hut.Students were told to suppose that they were planning to have a largetwo-topping pizza delivered to their residence that evening. The students had to decide between ordering from Pizza Hut at a reduced price of $8.49 (the regular price for a large two-topping pizza from the Oxford Pizza Hut at the time was$11.49) and ordering a pizza from a different pizzeria.
