find test statistic AND p value In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6964 subjectsrandomly selected from an online group involved with ears. There were 1302 surveys returned. Use a 0.01 significancelevel to test the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as anapproximation to the binomial distribution.Identify the null hypothesis and alternative hypothesis.A. Ho: p=0.2H₁: p>0.2C. Ho: p=0.2H₁: p=0.2E. Ho: p=0.2H₁: p<0.2The test statistic is z =(Round to two decimal places as needed.)B. Ho: p<0.2H₁: p=0.2D. Ho:p>0.2H₁: p=0.2F. Ho: p=0.2H₁: p=0.2

In a study of cell phone use and brain hemispheric dominance, an internet survey was e-mailed to 5000 subjects randomly selected from an online group involved with ears. 717 surveys were returned. Use a 0.01 significance level to test the claim that the return rate is less than 15%.
According to the U.S. Transportation Security Administration (TSA), 2% of the 771,556,886 travelers who utilized 440 federalized airports in 2017 waited more than 20 minutes in the TSA security line. The File TSAWaitTimes contains waiting Times in TSA security lines at a major U.S. airport for a recent random sample 10,531 travelers. Use these Data to test the hypothesis that the proportion of travelers waiting more than 20 minutes in TSA security lines at this airport is the same as the national proportion at α = .05 Data given: Time In Line Mean 11.99496 Median 11.97536 Standard Deviation 3.992043 Confidence Level(95.0%) 0.076253 Provide a 95% confidence interval with interpretation
A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage, u, of foodservice workers in the U.S. Last year's mean hourly wage was $8.25, and there is reason to believe that this year's value is less than last year's. The union decides to do a statistical test to see if the value has indeed decreased. The union chooses a random sample of this year's wages, computes the mean of the sample to be $7.98, and computes the standard deviation of the sample to be $1.25. Based on this information, answer the questions below. What are the null hypothesis (H) and the alternative hypothesis (H,) that should be used for the test? |Ho: u is ? H: u is ? v|? ? In the context of this test, what is a Type I error? v the hypothesis that u is ? A Type I error is ? fact, u is ? v when, in Suppose that the union decides not to reject the null hypothesis.

Small-business telephone users were surveyed 6 months after access to carriers other than Carrier A became available for wide-area.telephone service. Of a random sample of 280 Carrier A users, 151 said they were attempting to learn more about their options, as did 174 of an independent random sample of 220 users of alternate carriers. Test, at the 5% significance level against a two-sided alternative, the null hypothesis that the two population proportions are the same. Click the link to view a standard normal distribution table. Let P, be the proportion of Carrier A users who said they were attempting to learn more about their options and Py be the proportion of users of alternate carriers who said they were attempting to learn more about their options.

The Congressional Budget Office reports that 36% of federal civilian employees have a bachelor’s degree or higher (The Wall Street Journal). A random sample of 120 employees in the private sector showed that 33 have a bachelor’s degree or higher. Does this indicate that the percentage of employees holding bachelor’s degrees or higher in the private sector is less than in the federal civilian sector? Use alapha= .05 What is the null hypothesis? What is the alternative hypothesis? What distribution are you using? What test are you running? What is your conclusion?
A union of restaurant and foodservice workers would like to estimate the mean hourly wage, u, of foodservice workers in the U.S. this year The mean hourly Español wage last year was $8.08, and there is good reason to believe that this year's value is less than last year's. The union decides to do a statistical test to see if the value has indeed decreased. The union chooses a random sample of this year's wages, computes the mean of the sample to be $7.78, and computes the standard deviation of the sample to be $1.10.

A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data? Click the icon to view the data table. Determine the null and alternative hypotheses. i More Info O A. Ho: The amount of smoking is dependent upon seat be H: The amount of smoking is not dependent upon sea B.

In 2005, Health Canada claimed that 16.9% of Canadian adults are obese. A researcher wanted to check whether this percentage has decreased in 2009. He randomly selected 225 Canadian adults and found 33 of them are obese. Use3% significance level. Null and alternative hypothesis are H0: p < 0.169, H1: p >= 0.169 H0: mu >= 16.9, H1: mu < 16.9 H0: mu < 16.9, H1: mu >= 16.9 H0: p >= 0.169, H1: p < 0.169
