A survey by a national association is designed to estimate the proportion 100 member organizations reveals the following: Frontline employee tumover cost: X = $10,200, S = $1200. Forty-two member organizations have both talent and development programs in place to drive human-capital management. Complete parts (a) through (d) below. member organizations that have both talent and development programs in place to drive human-capital management as well as the member organizations' mean annual employee turnover cost. A random sample of a. Construct a 95% confidence interval estimate for the population mean frontline employee turnover cost of member organizations. (Round to two decimal places as needed.) b. Construct a 95% confidence interval estimate for the population proportion of member organizations that have both talent and development programs in place to drive human-capital management. (Round to four decimal places as needed.) c. What sample size is needed to have 99% confidence of estimating the population mean frontline employee turnover cost to within +$350? (Type a whole number.) d. How many member organizations need to be selected to have 90% confidence of estimating the population proportion of organizations that have both talent and development programs in place to drive human-capital management to within +0.045? Assume that the association's survey provides a reliable point estimate of the proportion. (Type a whole number.)
