Broccoli weight variation

Description

A number of growers supply broccoli to a food processing plant. The plant instructs the growers to pack the broccoli into standard size boxes. There should be 18 clusters of broccoli per box and each cluster should weigh between 1.33 and 1.5 pounds. Because the growers use different varieties, methods of cultivation etc, there is some variation in the cluster weights. The plant manager selected 3 growers at random and then 4 boxes at random supplied by these growers. 3 clusters were selected from each box.
