Two random samples were found, one from Japan and one from Scotland. The sample variances were found for both samples. The sample variance for Japan 2.247 and the sample variance for Scotland was 0.624. Test the claim that the population variance for Scottish companies is lower than that of Japanese companies. The P-value was found to be 0.0388. Use a 5% level of significance.
(Do Not Perform The Tests! Just answer the following)
a) Write the null and alternative hypothesis
b) Is it right, left, or two tailed?
c) Is it z, t, or x square or f distribution?
d) What calculator function is used?
e) What decision would you make based on the P-value that resulted when I did the test? Use a level of significance of 5%.

In a study of annual salaries of employees, random samples were selected from two companies to test if there is a difference in average salaries. For Company "X", the sample was size 65, the sample mean was $47,000 and the population standard deviation is assumed to be $11,000. For Company "Y", the sample size was 55, the sample mean was $44,000 and the population standard deviation is assumed to be $10,000. Test for a difference in average salaries at a...

A consumer agency has compiled grocery bills (in dollars) from random samples of supermarket customers in Florida and Georgia. Assuming the population variances are not equal, use the Excel output below to identify whether each of the following conclusions is correct. You must make a selection for each option. Click once to place a check mark for correct answers and click twice to place an "x" for the wrong answers. At the 2.5% significance level, conclude that the average grocery...

A nutritionist found that a random sample of sandwiches from two restaurants, labeled A and B, had the sample statistics shown in the table to the bottom right. Construct a 95% confidence interval for o/o using the definition to the right, where o and o are the variances of the cholesterol content of sandwiches from A and B, respectively. The 95% confidence interval is (OD). (Simplify your answer. Round to three decimal places as needed.) When s; and s are...

Test the indicated claim about the means of two populations. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use the traditional method or P-value method as indicated.
