An operator of a filling machine plotted the weights of each bag she filled for three weeks. at the same time, a quality inspector randomly took groups of five bags of the same output and plotted the average weights of the samples. the inspector's sampling distribution will: have a mean five times greater than the operator's distribution. show if the output has been produced to the operator's specifications. have less variability than the operator's distribution. have greater variability than the operator's distribution.
