- The U.S. Census Bureau reported that in 2015,the proportion of adult Americans age 25 and olderwho have a bachelor’s degree or higher is 0.325(“Educational Attainment in the United States:2015,” census.gov, retrieved January 22, 2017).Consider the population of all adult Americans age25 and over in 2015 and define 户to the proportionof people in a random sample from this populationwho have a bachelor’s degree or higher.a. Would 卢based on a random sample of only 10people from this population have approximatelya normal distribution? Explain why or why not.b. What 征e the mean value and standard deviation of户based on a random sample of size 400?c. Suppose that the sample size is n = 200 ratherthan n = 400. Does the change in sample sizeaffect the mean and standard deviation of thesampling distribution of 卢？ If so, what are thenew values for the mean and standard deviation?If not, explain why not.A doctor is interested in the proportion of patients which live at least 5 years after being diagnosed with stage 4 breast cancer. He randomly selects 96 patients diagnosed with stage 4 breast cancer and follows them for 5 years. Suppose the true 5 year survival rate for stage 4 breast cancer is 25%. How are the collection of all sample proportions of samples of size 96 distributed?N(, ) What is the probability that fewer than 22% of the patients studied survived for at least 5 years? List the zz-scores needed to calculate the result. If there is more than one zz-score, separate the values with a comma. There is a chance that fewer than 22% of the patients studied survived for at least 5 years. What is the probability that more than 33% of the patients studied survived for at least 5 years? List the zz-scores needed to calculate the result. If there is more than one zz-score, separate the values with a comma. There is a chance that more than 33% of the…In the midst of labor–management negotiations, the president of a company argues that the company’s blue-collar workers, who are paid an average of $30,000 per year, are well paid because the mean annual income of all blue-collar workers in the country is less than $30,000. That figure is disputed by the union, which does not believe that the mean blue-collar income is less than $30,000. To test the company president’s belief, an arbitrator draws a random sample of 350 blue-collar workers from across the country and asks each to report his or her annual income. If the arbitrator assumes that the blue-collar incomes are normally distributed with a standard deviation of $8,000, can it be inferred at the 5% significance level that the company president is correct?

- During the recovery from the Great Recession of 2007-2009, the economic situation for many familiesimproved. However, in 2011 the recovery was slow and it was uncertain as to how much had reallychanged on the national level. To estimate the national average of the percent of low-income workingfamilies, a representative simple random sample of the percent of low-income working families from eachof the country’s reporting jurisdictions could be used to calculate a point estimate and create a relatedconfidence interval. With this confidence interval a better picture of the nation’s recovery can be had andlegislative decisions can be made.6. Describe in two or three sentences how a simple random sample of size n=20 could be obtainedfrom the full list of jurisdictions provided for use with this assignment.7. A researcher reported that a sample of size n=30 produced a sample mean of 32.56% and a samplestandard deviation of 6.56%. Use this information to calculate a 90% confidence interval…‘Churn’ is a term used to describe the rate at which a company loses customers to itscompetitors. In the telecommunications industry, it is believed that the churn ratebetween cellphone service providers (e.g. Vodacom, MTN, Virgin Mobile, 8.ta andCell C) is not more than 15%.A telecommunications analyst surveyed a random sample of 560 cellphone subscribersand found that 96 of them had changed service provider within the past year.(a) Is there sufficient statistical evidence at the 10% significance level to concludethat the churn rate in the telecommunications industry exceeds 15%? Performa hypothesis test for a single proportion and report the findings.(b) compute the p-value for the test.Interpret the findings for the telecommunications analyst.
