Scores of students in a large Statistics class are normally distributed with a mean of 75 points and a standard deviation of 5 points. Find the probability that a student scores more than 80 points If 100 students are picked at random, how many do you expect to score below 70 points? If top 10% of students obtain an A grade, how much should a student obtain to get an A grade. Suppose four students are picked at random, find...
