Description of this paper

Calculate the ?t? value for independent groups for the following data using the formula presented in the module




Question;Any conclusion drawn for the t-test;statistical process is only as good as the research question asked and the null;hypothesis formulated. T-tests are only used for two sample groups, either on a;pre post-test basis or between two samples (independent or dependent). The;t-test is optimized to deal with small sample numbers which is often the case;with managers in any business. When samples are excessively large the t test;becomes difficult to manage due to the mathematical calculations involved.;Calculate the ?t? value for;independent groups for the following data using the formula presented in the;module. Check the accuracy of your calculations. Using the raw measurement data;presented above, determine whether or not there exists a statistically significant;difference between the salaries of female and male human resource managers;using the appropriate t-test. Develop a research question, testable hypothesis;confidence level, and degrees of freedom. Draw the appropriate conclusions with;respect to female and male HR salary levels. Report the required ?t? critical;values based on the degrees of freedom. Your response should be 2-3 pages.;Salary;Level;Female HR Directors;Male HR Directors;$50,000;$58,000;$75,000;$69,000;$72,000;$73,000;$67,000;$67,000;$54,000;$55,000;$58,000;$63,000;$52,000;$53,000;$68,000;$70,000;$71,000;$69,000;$55,000;$60,000;*Do;not forget what we all learned in high school about ?0?s;1. Calculate the ?t? value and set up;the posting as required.;2. Develope an appropriate research;question.;3. Develope an appropriate testable;hypothesis based on the research question.;4. Select an appropriate confidence;level and accurately stated the degrees of freedom along with the required;critical value for ?t.?
