I am interested in whether OSU males and females have the same grade point average. Use the table to perform a difference of means test and tell me the msult of the test. (Remember you have to calculate the variance for each variable using the equation with n1 in the denominator) 396 2.67 220 1. 98 _'E_ \" m IE._ _ 1) State the Null and Alternative Hypotheses. (5 points) 2) Establish your decision criteria and determine t critical (df = N1+N22). 3) What is the Standard Error of the mean difference? 4) Calculate t calculated? 5) Are the results statistically significant and explain what it means with respect to the Null hypothesis (20points)
