A Mail-Order Business Prides Itself in Its Ability to Fill

question 172

Multiple Choice

A mail-order business prides itself in its ability to fill customers' orders in six calendar days or less on the average. Periodically, the operations manager selects a random sample of customer orders and determines the number of days required to fill the orders. Based on this sample information, he decides if the desired standard is not being met. He will assume that the average number of days to fill customers' orders is six or less unless the data suggest strongly otherwise. On one occasion where a sample of 40 customers was selected, the average number of days was 6.65, with a sample standard deviation of 1.5 days. Can the operations manager conclude that his mail-order business is achieving its goal? Use a significance level of 0.025 to answer this question. Conduct the test using this p-value.

• A) Since 0.024 > 0.0041, reject the null hypothesis.
• B) Since 0.046 > 0.0025, reject the null hypothesis.
• C) Since 0.0046 < 0.025, reject the null hypothesis.
• D) Since 0.0024 < 0.041, reject the null hypothesis.
