travenous fluid bags are filled by an automated filling machine. Assume that the fill volumes of the bags are independent, normal random variables with a standard deviation of 0.08 fluid ounces. (a) What is the standard deviation of the average fill volume of 21 bags

The standard deviation of the average fill volume of 21 bags is 0.0175 fluid ounces

Step-by-step explanation:

To calculate the standard deviation of the average fill volume of 21 bags, we simply divide the standard deviation by the square root of variable number

That will be 0.08/√21 = 0.0175 fluid ounces
