Problem 4. A recent survey of students at University XYZ shows that for a specific statistics course, 1 in 5 students spent more than five hours per week on the course (outside of attending lectures and labs). Of the students who did not spend more than five hours per week on the course, 6.6% of them earned a B+ or higher in the course. Of the students who spent more than five hours a week on the course, 60.3% of them did not get a B+ or higher in the course. Use this information to answer the following questions. a. Complete the following contingency table. Please enter your answers as probabilities, not percentages or counts. Do NOT round any values in the table! Note: you must complete at least the table to receive any marks on this question. Source More than 5 Hours 5 Hours or Less Row Totals B+ or Higher Lower than B+ Column Totals
