A student at a four-year college claims that mean enrollment at four-year colleges is higher than at two-year colleges in the United States. Two surveys are conducted. Of the 35 four-year colleges surveyed, the mean enrollment was 5,466 with a standard deviation of 8,191. Of the 35 two-year colleges surveyed, the mean enrollment was 5,068 with a standard deviation of 4,777. Test the student's claim at the 0.10 significance level.a) The null and alternative hypothesis would be: H0:μF=μTH1:μF<μT H0:pF=pTH1:pF>pT H0:pF=pTH1:pF≠pT H0:pF=pTH1:pF<pT H0:μF=μTH1:μF>μT H0:μF=μTH1:μF≠μT b) Determine the test statistic.

PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. 1) In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.8 and a standard deviation of 1.51. Use a 0.10 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? A. H0: μ=0 mg/dL H1: μ<0 mg/dL B. H0: μ>0 mg/dL H1: μ<0 mg/dL C. H0: μ=0 mg/dL H1: μ≠0 mg/dL D. H0: μ=0 mg/dL H1: μ>0 mg/dL…
A simple random sample of 195 males was taken and their birth weights measured. The sample had a mean of 3272.8 g and standard deviation of 660.2 g. Use a 0.01 significance level to test the claim that the population mean of birth weights of males is less than 3400 g. Use the p-value method. Include a diagram of the distribution indicating important components of the question.
A basketball analyst recently claimed that the average number of passes per possession in basketball today is less than 5. A random sample of 40 possessions had a mean number of passes of 4.1.

A tire company claims that the lifetimes of its tires average 50,000 miles. The standard deviation of tire lifetimes is known to be 5,261 miles. You sample 100 tires and will test the hypothesis that the mean tire lifetime is at least 50,000 miles against the alternative that it is less. Assume, in fact, that the true mean lifetime is 49,545 miles. It is decided to reject Ho if the sample mean is less than 48,894. Find the level and power of this test. 0 Round your answers to four decimal places. Level of the test = Power of the test =
