A comparative study is done between students who study more than 12 hours for a final exam and those that study less than 12 hours for a final exam. The average final exam score of 200 students that studied more than 12 hours is 84% with a standard deviation of 20%. The average final exam score of 200 students that studied less than 12 hours is 79% with a standard deviation of 40%. At the 5% significance level determine if the average grade of those that study more than 12 hours is higher than those that don't. Take the students that study more than 12 hours as population 1. Give the hypotheses. Null: There is no difference in the average grade between those that study more than 12 hours and those that do not. Alternative: The average grade of those that study more than 12 hours is higher than those that do not. Null: There is no difference in the average grade between those that study more than 12 hours and those that do not. Alternative: The average grade of those that study more than 12 hours is less than those that do not. Null: There is no difference in the average grade between those that study more than 12 hours and those that do not. Alternative: The average grade of those that study more than 12 hours for a final is not equal to those that do not.
