We would like to conduct a hypothesis test of Ho: = 50 vs. Ha: 50 for the meanof some normally distributed variable X. A random sample of 25 observations is takenfrom the population. A 90% confidence interval for u is calculated to be (44.46, 49.58).A 96% confidence interval for p is calculated to be (43.82, 50.22). The P-value of theappropriate test of significance must be:(A) less than 0.04.(B) greater than 0.10.(C) between 0.02 and 0.05.(D) between 0.04 and 0.10.(E) equal to 0.06.JK

For a population data set sigma = 12.7 How large a sample should be selected so that the margin of error of estimate for a 96 confidence interval for u is 3.20?
In a random sample of seven people, the mean driving distance to work was 22.1 miles and the standard deviation was 5.1 miles. Assuming the population is normally distributed and using the t-distribution, a 95% confidence interval for the population mean μ is (17.4, 26.8) (and the margin of error is 4.7). Through research, it has been found that the population standard deviation of driving distances to work is 5.6. Using the standard normal distribution with the appropriate calculations for a standard deviation that is known, find the margin of error and construct a 95% confidence interval for the population mean μ. Interpret and compare the results. Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. It can be said that enter your response here % of the population has a driving distance to work (in miles) that is between the interval's endpoints. B.…
Prior to the initiation of a student retention program against student dropout in a metropolitan city, a survey revealed that 250 members of a sample of 600 young people at the university level had been detected as dropouts. Are these data compatible with the view that 50 percent of the young people in that city had been detected as dropouts? Work with a significance level of 5%.1. The parameter of interest is:2. The hypotheses for this test are:3. The calculated test statistic is:4. The critical region is:5. Draw the critical region (make a decision):6. It can be concluded that:

If an experimenter wishes to use a "known" value o = 1.0 for the standard deviation of the resilient modulus measurements based upon prior experience, construct appropriate 90%, 95%, and 99% two-sided confidence intervals for the average resilient modulus µ. Compare the lengths of the confidence intervals. Do you think it is plausible that the average resilient modulus is equal to 20.0?

One study compared the differences between the expected values of two groups, i.e. tested the null hypothesis that the expected values are equal. The sample size of the first group (x-observations) was 55 and the sample size of the second group (y-observations) was 60. The following data was obtained.X=113.6, Y= 111.7S2x=32.4S2y=30.1Assume large sample sizes and use a test size and two-tailed test appropriate for this setting. Calculate the p-value of the test.
