MGT 340 Assignment 2: T-Test for Difference in Salaries
T-Test 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 . 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 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 0s
