You may need to use the appropriate appendix table or technology to answer this question.Barron's reported that the average number of weeks an individual is unemployed is 16.5 weeks. Assume that for the population of all unemployed individuals the population mean length of unemploymentis 16.5 weeks and that the population standard deviation is 5 weeks. Suppose you would like to select a sample of 50 unemployed individuals for a follow-up study.(a) Show the sampling distribution of x, the sample mean average for a sample of 50 unemployed individuals.^1.5 6.5 11.5 16.5 21.5 26.5 31.5A-2.1-1.4 -0.7 0 0.7 1.4 2.1weeksweeks47.9 48.6 49.3 50 50.7 51.4 52.1weeks14.4 15.1 15.8 16.5 17.2 17.9 18.6weeks(b) What is the probability that a simple random sample of 50 unemployed individuals will provide a sample mean within 1 week of the population mean? (Round your answer to four decimal places.)(c) What is the probability that a simple random sample of 50 unemployed individuals will provide a sample mean within -week of the population mean? (Round your answer to four decimal places.)

A clinical microbiology laboratory compared the frequency of isolation of DNA hybridization probe to a culture method for the sexually transmitted bacterium Neisseria gonorrhaeae. The frequency of isolation from clinical specimens was historically 10%. The lab ran 100 split samples, and the results are presented in the table below. Table.

One of the samples came from measured weights, whereas the other sample resulted from asking people what they weigh. Identify which distribution came from which sample. Explain how you came to that conclusion. Notice that you can make a conclusion about the nature of the data by simply examining the distributions. Next, construct an “ideal” distribution of last digits x that would result from 100,000 people who were actually weighed. Estimate the mean and standard deviation of the last digits x in the ideal distribution. Finally, explicitly agree or disagree with the posts of at least 2 of your peers, and explain why you agree or…

t Test for TWO DEPENDENT (Related) SAMPLES (Show all work) A manufacturer of a gas additive claims that it improves gas mileage. A random sample of 40 drivers tests this claim by determining their gas mileage for a full tank of gas that contains the additive (X1) and for a full tank of gas that does not contain the additive (X2). The sample mean difference D-Bar equals 2.12 miles (in favor of the additive) and the estimated standard error equals 1.50 miles. Test the Null Hypothesis with t, using the .05 Level of significance and construct a 95 percent confidence interval (whether you reject OR retain the Null Hypothesis)
