A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.75lb, the mean of all of the weights is x=2.096 lb, and the standard deviation of the weights is s=2.152 lb. a. What is the difference between the weight of 5.75 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 5.75 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 significantly high, is the weight of 5.75lb significant? Question content area bottom Part 1 a.
