According to The World Factbook, 2004, the total fertility rate (estimated mean number of children born per woman) for Madagascar is 5.4. Suppose that the standard deviation of the total fertility rate is 3.7. The mean number of children for a sample of 220 randomly selected women is one value of many that form the SDSM. (a) What is the mean value for this sampling distribution? (Give your answer correct to one decimal place.) (b) What is the standard deviation of this sampling distribution? (Give your answer correct to two decimal places.)
