A data set lists weights(lb) of plastic discarded by households. The highest weight is 5.51 lb, the mean of all of the weights is x=2.378 lb, and the standard deviation of the weights is s=1.751 lb.

a. What is the difference between the weight of 5.51 lb and the mean of theweights?

b. How many standard deviations is that[the difference found in part(a)]?

c. Convert the weight of 5.51 lb to a z score.

d. If we consider weights that convert to z scores between 2 and 2 to be neither significantly low nor significantlyhigh, is the weight of 5.51 lbsignificant?
