A college has over 5,000 students, 10% of which are left-handed. A new lecture hall is being planned that will seat 300 students, and college officials want to be sure there are enough left-handed desks. Suppose we
randomly select groups of 300 students from this college.
What are the mean and standard deviation of the number of left-handed students in each group of 300?
