In 2016, the Pew Research Center reported the results of a survey about public library usage. A nationally representativ sample of 1601 people aged 16 and older who were living in the United States completed the survey. One survey question asked whether the survey respondent had visited, in person, a library or a bookmobile in the last year. A total of 768 of those surveyed answered "yes" to this question. Although the samples in national polls are not simple random samples, the are similar enough that our method gives approximately correct confidence intervals. Give a 99% confidence interval for the proportion of all American adults who answered yes on the survey question. (Use the table of critical values of the Normal distributions. Give your answer as an interval in the form (lower limit, upper limit). Use decimal notation. Give the limits to two decimal places.) 99% confidence interval:

Matrimo.., ..onthly is a top-selling magazine that provides information for couples thinking about marriage. Over the years, writers for the magazine have researched just about everything there is to research about weddings. The popular conception at the magazine has been that roughly 50% of first weddings take place indoors in a church, 30% take place indoors in a building other than a church, and 20% take place outdoors. This past week, the magazine examined a random sample of 280 first weddings and found the distribution given by the first row of numbers in the table below. (This row contains the frequencies observed in their sample of 280.) The second row of numbers gives the frequencies expected under the hypothesis that the popular conception at the magazine is correct. The bottom row of numbers contains the following value for each of the wedding location categories. 2 (Observed frequency – Expected frequency) Expected frequency Part 1 (fo-fE) Fill in the missing values in the…

Cyberbullying In 2018, the Pew Research Center did a study on cyberbullying. A sample of 743 teens were asked if they had ever experienced any of the below 6 types of cyberbullying while online or via their cellphone. Those who selected yes to one or more of these questions were considered to be a target of cyberbullying. (Source: Pew Research Center, September 2018, "A Majority of Teens Have Experienced Some Form of Cyberbullying") Offensive name-calling Spreading of false rumors Receiving explicit images they didn't ask for Constant asking of where they are, what they're doing, who they're with, by someone other than a parent Physical threats Having explicit images of them shared without their consent a.) A total of 438 of the sampled teens were considered a target of cyberbullying. Find a 92% confidence level for the proportion of all teens in the U.S. who are a target of cyberbullying.

Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation. What are the degrees of freedom?
Kim Kardashian is interested in studying the phenomenon of selfies more deeply. She randomly selects 20 of her Instagram followers' feeds.

River Run campground has sites for people to use for camping. The sites can be reserved for a certain number of days. To help with cleaning and maintenance, the campground requests an exit time (the time at which campers leave the site) of 9 A.M. on the last day of the reservation. To estimate the typical exit time, the manager of River Run selected a random sample of 60 sites. Of the selected sites, 40 were reserved by people without young children, and 20 were reserved by people with young children. The following histograms summarize the exit times, recorded as minutes relative to 9 A.M. For example, an exit time of 9:30 A.M. is 30 minutes relative to an exit time of 9 A.M. Each interval contains possible values from the left endpoint up to but not including the right endpoint. Compare the two histograms. How many of the 60 sites had an exit time before 8:30 A.M.? How many of the 60 sites had an exit time of 11:00 A.M. or later? Compare the distributions of the exit times for…
