A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.24 Ib, the mean of all of the weights is x=2.208 lb, and the standard deviation of the weights is s = 1.971 Ib. a. What is the difference between the weight of 5.24 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.24 Ib to a z score. d. If we consider weights that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the weight of 5.24 Ib significant?
