A mail-order company has 2 warehouses. Independent surveys show that 364 out of 400 orders placed with Warehouse One and 279 out of 300 orders placed with Warehouse Two were mailed on time. Perform a hypothesis test to determine whether the samples provide strong evidence that the on-time percentage of orders placed at Warehouse One is lower than that at Warehouse Two. (a)Clearly state the test hypotheses. Begin with “Let ….. represent ….., respectively.” (b)Use an appropriate formula to calculate the test statistic. (c)Use an appropriate table to find the p-value. Do not draw any conclusion
