TABLE 8-1 A Random Sample of 100 Stores from a Large Chain

question 21

True/False

TABLE 8-1
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.
-Referring to Table 8-1, if the population had consisted of 1,000 stores, the confidence interval estimate of the mean with finite population correction would have been wider in range.
