A stats instructor was horrified to see that the distribution of N = 53 homework scores had a mean of u = 73. However, the instructor realized that this mean included scores from five students who didn't turn in any assignment (i.e., who had been given scores of 0). If she wanted to re-compute the mean to evaluate the performance for only the students who did turn in their homework, what would be the new mean for those students?
