Suppose a company finds that the mean number of sick days used per year by their employees is 7 days with a standard deviation of 2 days. In a random sample of 180 employees the mean number of sick days used per year was 6.8 days. (a) Give the parameter and the statistic. Don't forget that your answer should be in contert! (b) What is the probability that in a sample of 180 employees the mean number of sick days used per year is less than or equal to 6.8 days? (c) Suppose the company enacts a new policy where it pays time and a half for each unused sick day. A year after the policy was in place, the company took a random sample of 100 employees and found that the mean number of sick days used is 6. Does it seem like the policy affected the employees use of sick days? Be sure to mathematically support your claim!
