A headline in a certain newspaper states that "most stay at first job less than 2 years."
That headline is based on an online poll of 320 college graduates. Among those polled,
72% stayed at their first full-time job less than 2 years. a. Assuming that 50% is the true
percentage of graduates who stay at their first job less than two years, find the mean and
standard deviation of the numbers such graduates in randomly selected groups.
I know how to get the mean and standard deviation I am just not sure how to do it in this problem. I have been trying to figure it out for two hours
