SCENARIO 8-16
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 Scenario 8-16,we do not know for sure whether the true population mean is between 5.623 and 6.377 lawnmowers sold.

This statement is true because the confidence interval only provides an estimate of the range of values within which the true population mean is likely to fall, with a given level of confidence. It does not guarantee that the true population mean falls within this range with 100% certainty.
