The mean of the 1000 birthweights in Table 6.2 is 112.0 oz with standard deviation 20.6 oz. A) If the central-limit theorem holds, what proportion of the sample means should fall within 0.5 lb of the population mean (112.0 oz)? B) Answer Problem 6.52 for 1 lb rather than 0.5 lb. C) Compare your results in Problems 6.52 and 6.53 with the actual proportion of sample means that fall in these ranges. D) Do you feel the central-limit theorem is applicable for samples of size 5 from this population? Explain.

Question

Figure 6.4b (p. 172) plotted the sampling distribution of the mean from 200 samples of size 5 from the population of 1000 birthweights given in Table 6.2. The mean of the 1000 birthweights in Table 6.2 is 112.0 oz with standard
deviation 20.6 oz.

A) If the central-limit theorem holds, what proportion of the sample means should fall within 0.5 lb of the population mean (112.0 oz)?

B) Answer Problem 6.52 for 1 lb rather than 0.5 lb.

C) Compare your results in Problems 6.52 and 6.53 with the actual proportion of sample means that fall in these ranges.

D) Do you feel the central-limit theorem is applicable for samples of size 5 from this population? Explain.
