Astudy was made to determine if the subject matter in a physics course is better understood when a lab constitutes part of the course. students were randomly selected to participate in either a 3-semesterhour course without labs or a 4-semester-hour course with labs. in the section with labs, 11 students made an average grade of 85 with a standard deviation of 4.7, and in the section without labs, 17 students made an average grade of 79 with a standard deviation of 6.1. would you say that the laboratory course increases the average grade by as much as 8 points? use a p-value in your conclusion and assume the populations to be approximately normally distributed with equal variances. g
