Part D , please.
Transcribed Image Text:A survey by a national association is designed to estimate the proportion of 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 100 member organizations reveals the following:
Frontline employee turnover cost: X= $13,200, S = $1000. Forty member organizations have both talent and development programs in place to drive human-capital management.
Complete parts (a) through (d) below.
a. Construct a 99% confidence interval estimate for the population mean frontline employee turnover cost of member organizations.
12937.36 s us 13462.64
(Round to two decimal places as needed.)
b. Construct a 99% confidence interval estimate for the population proportion of member organizations that have both talent and development programs in place to drive human-capital management.
0.2311 STS 0.3089
(Round to four decimal places as needed.)
c. What sample size is needed to have 90% confidence of estimating the population mean frontline employee turnover cost to within ±$200?
68
(Type a whole number.)
d. How many member organizations need to be selected to have 95% confidence of estimating the population proportion of organizations that have both talent and development programs in place to drive human-capital management to within
+0.065? Assume that the association's survey provides a reliable point estimate of the proportion.
