According to a USPS study, the weight of a randomly selected shipment box is normally distributed
with a mean of 21.3 lbs and a standard deviation of 4.7 lbs. Let x be the weight of a randomly
selected shipment box and let S be the total weight of a random sample of size 23 .
Describe the probability distribution of x and state its parameters mu and sigma :
x∼ Select an answer vv(mu =,sigma =,)
and find the probability that the weight of a randomly selected shipment box is between 12 and 13
lbs.
