Hey. I need to know HOW to get the exact p-value. I'm not asking for the answer, I need to know how you got it. Please only use a TI-83 or EXCEL.
On the basis of data provided by a salary survey, the variance in annual salaries for seniors in public accounting firms is approximately 2.3 and the variance in annual salaries for managers in public accounting firms is approximately 11.3. The salary data were provided in thousands of dollars. Assuming that the salary data were based on samples of 25 seniors and 26 managers, test to determine whether there is a significant difference between the variances of salaries for seniors and managers. At a 0.05 level of significance, what is your conclusion?
Question: Find the p-value. (Round your answer to four decimal places.)

4. The Philadelphia office of Price Waterhouse Coopers LLP hired five accounting trainees this year. Their monthly starting salaries were: $3,536; $3,173; $3,448; $3,121; and $3,622 (10 marks) (a) Compute the population mean. (b) Compute the population variance. (c) Compute the population standard deviation. (d) The Pittsburgh office hired six trainees. Their mean monthly salary was $3,550, and the standard deviation was $250. Compare the two groups.
