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
s^2 = .07454

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
