The Plant Manager Believes That the Temperature in the Packaging

Multiple Choice

The plant manager believes that the temperature in the packaging area of the plant affects the daily rate of production. To investigate, the plant temperature is set at 18 degrees, 20 degrees, and 22 degrees. The number of units produced at each of these temperatures for a sample of days is collected. Using this output, what conclusions can you draw?

A) The total size of the sample used was 24.
B) Since the P-value is 0.0024, there is a 2% chance of these results happening when there is no significant difference in the number of units produced at the three temperatures.
C) Since the calculated F-value is large, and the P-value is so small, there is strong evidence to suggest that the number of units produced at the three temperatures is all the same.
D) Since the calculated F-value is large, and the P-value is so small, there is strong evidence to suggest that the number of units produced at the three temperatures is not all the same.
