Suppose that random samples of US workers from 2 major cities were collected, and the way they commute to work was documented. The results of the study are below.
A fragile product will be transported by road or rail. Since the railway is cheaper, this transportation route will be preferred if the breakage rate is less than 5% in the railway. In the table below, the amount of products transported by both ways and the transportationThe number of broken ones is given. Accordingly, which transportation route should be preferred at the 5% significance level?
State four ways to detect the presence of multicollinearity.
The Los Angeles City Controller's office calculated that in 2013, the city employed 4703047030 full‑time employees and 1014210142 part‑time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part‑time workers into full‑time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per‑event employees) who are full‑time employees ?p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per‑event employees) in June 2014 and found that 845845 were full‑time employees and 155155 were part‑time employees. If the advocacy group planned to use a one‑sample z-z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be Assume…
The Monterey Bay Aquarium, founded in 1984, is situated on the beautiful coast of Monterey Bay in the historic Cannery Row district. In 1985, the aquarium began a survery program that involved randomly sampling visitors as they exit for the day. The survey includes visitor demographic information, use of social media, and opinions on their aquarium visit. In 2015, the survey included 356356 visitors over age 6565 , of which 5252 used a mobile device such as an Android phone or iPad during their visit. (b) How large a sample ?n , is needed to get the common ±3±3 percentage point margin of error? Use the 2015 sample as a pilot study to get ?∗p∗ . (Enter your answer as a whole number.)
Each March, the Current Population Survey (CPS) is expanded to gather a wider variety of information than what is collected in the monthly reports. Suppose in one March survey, we are interested in participants whose highest level of education is a bachelor’s degree and who are between the ages of 25 and 64. It turns out that 14,959 of the survey respondents fall into this category. Think of them as a population. A) To select an SRS of these people, how would you assign labels? B) Use table 7.1, starting at line 107 choose the first three members of the SRS.

A company studied the number of lost-time accidents occurring at its brownsville,Texas, plant. historical records show that 6% of the employees suffered lost-time accidents last year. Management believes that a special safety program will reduce suchaccidents to 5% during the current year. In addition, it estimates that 15% of employeeswho had lost-time accidents last year will experience a lost-time accident during thecurrent year.a. What percentage of the employees will experience lost-time accidents in bothyears?
According to the February 2008 Federal Trade Commission report on consumerfraud and identity theft, 23% of all complaints in 2007 were for identity theft. Inthat year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumercomplaints ("Consumer fraud and," 2008). Does this data provide enoughevidence to show that Arkansas had a higher proportion of identity theft than23%? Test at the 5% level.
Alcohol abuse has been described by college presidents as the number one problem on campus, and it is an important cause of death in young adults. How common is it? A survey of 10,904 randomly selected U.S. college students collected information on drinking behavior and alcohol-related problems. The researchers defined “frequent binge drinking” as having five or more drinks in a row three or more times in the past two weeks. According to this definition, 2486 students were classified as frequent binge drinkers. Construct and interpret a 99% confidence interval for the proportion of students who are classified as binge drinkers. (Use the four-step process.) What would you include in "State" from the 4-step process?

Construct and interpret a 99% confidence interval for the proportion of students who are classified as binge drinkers. (Use the four-step process.) In the normal condition, np is 8,418, which is greater than 10 so the normal condition is met. Is this statement true or false?
