the mean wail time for a telephone reservation agent at a large airline is 40 seconds A manager with the airline is concerned that business may be lost due to customers having to wait too long for an agent To address this concern the manager develops new airline reservation policies that are intended to reduce the amount of time an agent needs to spend with each customer A random sample of 250 customers results in a sample mean wait time of 39 3 seconds with a standard deviation of 4 2 seconds Using a 0 05 level of significance do you believe the new policies were effective in reducing wait time Do you think the results have any practical significance State the conclusion in context of the problem There is sufficient evidence at the a 0 05 level of significance to conclude that the new policies were effective Do you think the results have any practical significance A No because the test concluded that there is no significant difference between the two mean wail times Therefore there is no practical significance OB No because while there is significant evidence that shows the new policies were effective in lowering the mean wait time of customers the difference between the previous mean wail time and the new mean wait time is not large enough to be considered important OC Yes because the test concluded that there is a significant difference between the two mean wait times Therefore there is a practical significance D Yes because while there is no significant evidence that shows the new policies were effective in lowering the mean wait time of customers the difference between the previous mean wait time and the new mean wait time is large enough to be considered important
