Question
A chip manufacturer wants to estimate the average fill for a package of chips. The data in the table represents a 1 in 100 systematic sample for 1 day’s production. Estimate the mean fill in ounces. Place a bound on the error of estimation. Assume the company produces about 3600 bags of chips per day.
Sum of values listed = 568.580; Sum of values^2 = 8980.283817

Explanation / Answer
Mean Estimate =Sum of values listed / No. of values
= 568.580 /36
= 15.794
Error estimate = S^2 /n
= 0.07454 /36
=0.0455
