A sample of 200 students at a Big-Ten university was taken after the midterm to ask them whether they went bar hopping the weekend before the midterm or spent the weekend studying, and whether they did well or poorly on the midterm. The following table contains the result.
Did Well in Midterm
Studying for Exam 80
Did Poorly in Midterm

70
Went Bar Hopping 30
If the sample is a good representation of the population, we can expect percent of the students in the population to spend the weekend studying and do poorly on the midterm.
