A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 138 ounces and a standard deviationityof 0.40 ounce. You randomly select 50 cans and carefully measure the contents. The sample mean of the cans is 137.9 ounces. Does the machineerdneed to be reset?

This looks like another problem. Read carefully. Sergio is doing a long hike and is carefully calculating his pack weight. An energy bar has mean weight 1.71 ounces and standard deviation 0.037. The weights of the bars are independent. A juice box has mean weight 7.1 ounces and standard deviation 0.25. The weights of the juice boxes are independent. If he takes 3 energy bars and 5 juice boxes, what will be the MEAN of the total weight in pounds from these items? Hint: If W is the weight in ounces, then W/16 is the weight in pounds.
