I want help having a mathematical issue A store-manager is attempting to determine whether to cost pears by fat, having a fixed-cost per-pound, or from the item, having a fixed-cost per lemon. He's worried that clients may pick the biggest types when there is a fixed-price per lemon. For just one week the pears are listed from the item in the place of by fat, and during this period the mean weight of the pears bought is documented for several clients who purchase 4 of these. The supervisor understands the populace of loads of personal pears is bell shaped with mean of 8 ounces along with a standard deviation of 1.6 ounces. When the 4 pears each client decides are equal to a random test, what must be the rough mean and standard deviation of the submission of the mean loads of 4 oranges?A. mean= 32 ounces, standard deviation = 6.2 ouncesB. mean=8 ounces, standard deviation = 1.6 ouncesC. mean=8 ounces, standard deviation = 0.8 ouncesD. mean=2 ounces, standard deviation = 0.4 ounces
