question 31

True/False

TABLE 8-12
A random sample of 100 stores from a large chain of 500 garden supply stores was selected to determine the mean number of lawnmowers sold at an end-of-season clearance sale.The sample results indicated a mean of 6 and a standard deviation of 2 lawnmowers sold.A 95% confidence interval (5.623 to 6.377)was established based on these results.
-True or False: Referring to Table 8-12,if the population had consisted of 400 stores,the confidence interval estimate of the mean with finite population correction would have been wider in range.
