ClairLinx Wireless, a start-up cell phone company, has divided its market of potential customers into three major groups: single, working; married, working; and retired. ClairLinx surveyed 500 potential customers and asked each, "Of the following, which do you consider to be the most important feature in a cell phone service plan: free nights and weekends, free long distance and roaming, or free calls to customers with the same company?" Each of the 500 potential customers in the survey was categorized according to the service plan feature she considers most important and the customer group in which she appears. The data are summarized in the contingency table below. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, type of potential customer and choice of service plan feature, are independent. Round the responses to at least two decimal places. Note:…

This question refers to a survey of a university's faculty members on affirmative action policies for the university. The survey was based on telephone interviews with a random sample of 1,001 faculty members conducted in December 1995. One of the questions asked was, "Do you favor or oppose using race, religion, sex, color, ethnicity, or national origin as a criterion for admission to the university?" Of the 165 arts and humanities faculty members, 63% favored the policy, while of the 223 engineering, mathematical, and physical sciences faculty, 37% favored it. (Round your answers to one decimal place.) (a) Find the conservative margin of error (as a percent) for the arts and humanities faculty. % Use the conservative margin of error to compute an approximate 95% confidence interval for the percent of them in the population who favored this policy. , % (b) Find the conservative margin of error (as a percent) for the engineering and sciences faculty. % Use the…
2. The Department of Fish and Wildlife looked at the ages of individuals between 65 and 81 that frequented the Bolsa Chica Reserve during the week of June 13th, 2021, to help determine if more facilities and resources are necessary to support the needs of that age group. They determined there were 40 individual visitors that fit those criteria, with the following ages: 65, 66, 66, 67, 67, 67, 68, 68, 68, 68, 69, 69, 69, 69, 69, 69, 70, 70, 70, 70, 70, 71, 71, 71, 71, 72, 72, 72, 73, 73, 73, 74, 74, 75, 75, 76, 77, 78, 79, and 80.

In recent years, many states have enacted tougher voter identification laws requiring a government issued photo ID. Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws. Document your work in the space provided below. Document how you computed the margin of error and the confidence interval in the space provided below. Round all numbers to 4 decimal places. 2)Is it likely that three-fourths of adults approve of these new laws?
Thirty-five percent (35%) of the population in a small community outside of Brownsville, Texas are Spanish-speaking American citizens. A Spanish-speaking person is arrested and accused of drug trafficing that resulted in the death of a non-Spanish-speaking American. The case goes to trial. Of the first 16 potential jurors who are interviewed, only 1 Spanish-speaking American is chosen to be on the jury, and 15 are not. The defendant's lawyer challenges the jury selection, claiming bias against her client. The government lawyer disagrees, saying that the probability of this particular jury composition is common and not unusual. Using Excel, (A) Compute the probability of selecting 1 Spanish-speaking Americans on the jury: (B) How many Spanish-speaking jurors would you expect? (C ) Compute the standard deviation of the probability distribution:
