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. Use = 0.05. Establish the appropriate null and alternative hypotheses to be tested for boxes that are supposed to have an average of 24 ounces.A) H0 : = 32 ounces Ha : 32 ounces
B) H0 : = 16 ounces Ha : 16 ounces
C) H0 : = 22 ounces Ha : 22 ounces
D) H0 : = 24 ounces Ha : 24 ounces
Question 2
Applebee's International, Inc, is a U.S. company that develops, franchises, and operates the Applebee's Neighborhood Grill and Bar restaurant chain.
It is the largest chain of casual dining restaurants in the country, with over 1,500 restaurants across the United States. The headquarters is located in Overland Park, Kansas. The company is interested in determining if mean weekly revenue differs among three restaurants in a particular city. The file entitled Applebees contains revenue data for a sample of weeks for each of the three locations.Test to determine if blocking the week on which the testing was done was necessary. Use a significance level of 0.05.A) The p-value = 0.078 > = 0.05. This indicates that inserting the week on which the testing was done was necessary.
B) The p-value = 0.078 > = 0.05. This indicates that inserting the week on which the testing was done was not necessary.
C) The p-value = 0.000 < = 0.05. This indicates that inserting the week on which the testing was done was necessary.
D) The p-value = 0.000 < = 0.05. This indicates that inserting the week on which the testing was done was not necessary.
