A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.48 lb, the mean of all of the weights is x=2.057 lb, and the standard deviation of the weights is s=2.263 lb.

What is the difference between the weight of 5.48 lb and the mean of the weights?

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

Convert the weight of 5.48 lb to a z score.

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 5.48 lb significant?
