Assume that 60% of community college students are female.
1) if we pick 100 students at random justify why we can or cannot model this using a normal model.
2) find the probability that between 50 and 70 of the 100 students selected are female.
3) fidn Q1 and Q3 for the middle 50% for the percent of female students chosen out of 100.
