A random sample of 175 students was selected from a large high school. They were each asked their current grade level and whether they have a driver's license. The responses are displayed in the table. Grade Level 9th 10th 11th 12th Yes 1 5 21 20 48 Driver's License?

The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 12.43, so all expected counts are at least 5. O Yes, the smallest expected count is 16.57, so all expected counts are at least 5. O No, the smallest expected count is 1.87, so the expected counts are not all at least 5. O No, the smallest expected count is 3.45, so the expected counts are not all at least 5.
