According to a recent publication, the total fertility rate (estimated mean number of children born per woman) for Madagascar is 5.2. Suppose that the standard deviation of the total fertility rate is 3.9. The mean number of children for a sample of 217 randomly selected women is one value of many that form the SDSM.

(a) What is the mean value for this sampling distribution? (Round your answer to one decimal place.)
(b) What is the standard deviation of this sampling distribution? (Round your answer to two decimal places.)
(c) Describe the shape of this sampling distribution.
