The makers of Mini-Oats Cereal have an automated packaging machine that can be set at any targeted fill level between 12 and 32 ounces. Every box of cereal is not expected to contain exactly the targeted weight, but the average of all boxes filled should. At the end of every shift (eight hours), 16 boxes are selected at random and the mean and standard deviation of the sample are computed. Based on these sample results, the production control manager determines whether the filling machine needs to be readjusted or whether it remains all right to operate. At the end of a particular shift during which the machine was filling 24-ounce boxes of Mini-Oats, the sample mean of 16 boxes was 24.32 ounces, with a standard deviation of 0.70 ounce. Assist the production control manager in determining if the machine is achieving its targeted average using test statistic and critical value t. Conduct the test using a p-value. A) p-value = 0.0872 0.025; therefore do not reject H0 B) p-value = 0.0422 0.005; therefore do not reject H0 C) p-value = 0.0314

Question

Assist the production control manager in determining if the machine is achieving its targeted average using test statistic and critical value t. Conduct the test using a p-value. A) p-value = 0.0872 > 0.025; therefore do not reject H0 B) p-value = 0.0422 > 0.005; therefore do not reject H0 C) p-value = 0.0314 < 0.105; therefore reject H0 D) p-value = 0.0121< 0. 0805; therefore reject H0

Quizplus · Accepted Answer

The p-value of 0.0872 is greater than the common alpha level of 0.05, indicating that the sample mean is not significantly different from the population mean (24 ounces), so there's insufficient evidence to suggest the machine is not achieving its targeted average.
