K A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.26 lb, the mean of all of the weights is x=2.312 lb, and the standard deviation of the weights is s = 1.118 lb. a. What is the difference between the weight of 5.26 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 5.26 lb to a z score. d.
