Assume that the true proportion of all full-time workers in the field who leave their jobs in order to retire is p 0.04. In a random sample of 1050 full-time workers in the field, let prepresent the proportion who leave their jobs in order to retire. Complete parts a through e below Click Here for StatCrunch a. Describe the properties of the sampling distribution of p. The mean of the sampling distribution of pis The standard deviation of the sampling distribution of pis (Round to four decimal places as needed.) b. Compute P(p<0.06) The probability that is less than 0.06 is (Round to four decimal places as needed.) Interpret this result in the field has a of workers that leave the job in order to retire 0.06 is The probability that the calculated probability c. Compute p >0.028) The probability that is greater than 0.028 is (Round to four decimal places as needed.) Interpret this result in the field has a of workers that leave the job in order to retire The probability that the calculated probability 0.028 is
