The grade point averages of 75 students who dropped out of the same course have a standard deviation of 0.762. Do the data indicate a difference between the variances of grade point averages for students who completed a financial accounting course and students who dropped out? Use a 0.05 level of significance. Let the students who completed the course be represented by population 1. Note: F0.025 with 340 and 74 degrees of freedom is 1.46. State the null and alternative hypotheses. Ho :o Hq: - Select your answer - 1 o. - Select your answer - so Reject Ho if F - Select your answer - A Calculate the value of the test statistic (to 2 decimals). What is your conclusion? - Select your answer - AH

Answer 1

On the basis of given information:

Ho: Is equal to

Ha: Is not equal to

Reject Ho if F > 1.46

Test statistic = (0.945)² / (0.762)² = 1.54

Reject Ho
