Part A A store sells ground meat in small, medium, and large sizes. The weights of the small size packages have a mean weight of 1 pound and a standard deviation of 0.1 pound. If the distribution of weights for the small size packages of ground meat is approximately normally distributed, what is the best estimate of the probability that a randomly selected small size package has a weight less than 0.9 pound? Part B  A student measures the wingspans of 40 local dragonfly specimens selected at random. The sample mean is 7.2 centimeters with a margin of error of 1.3 centimeters. Based on this information, what are plausible values for
