A human resources manager keeps a record of how many years each employee at a large company has been working in their current role. The distribution of these years of experience are strongly skewed to the right with
a mean of 3 years and a standard deviation of 2 years. Suppose we were to take a random sample of 4
employees and calculate the sample mean for their years of experience. We can assume independence between
members in the sample.
What is the probability that the mean years of experience from the sample of 4 employees ž is greater than
3.5 years?
