Answer:
24 boxes
Step-by-step explanation:
The processor knows that the standard deviation of box weight is 0.5 pound
We are supposed to find How many boxes must the processor sample to be 95% confident that the estimate of the population mean is within 0.2 pound
Formula of Error=
Since we are given that The estimate of the population mean is within 0.2 pound
So,
z at 95% confidence level is 1.96
Hence the processor must sample 24 boxes to be 95% confident that the estimate of the population mean is within 0.2 pound
Im guessing how many inches are 22 because it makes sense
