Question

Determine whether the current average frame weight is acceptable, or whether it should be reduced.

Answer 1

The machine needs to be recalibrated because the standard deviation of the 84 boxes is greater than the allowable standard deviation of 0.5 ounces.

Step-by-step explanation:

To determine if the machine needs to be recalibrated, we need to compare the standard deviation of the 84 boxes to the allowable standard deviation of 0.5 ounces. If the standard deviation of the 84 boxes is greater than 0.5 ounces, then the machine needs to be recalibrated. In this case, the standard deviation is 0.54 ounces, which is greater than 0.5 ounces. Therefore, the machine needs to be recalibrated.
