A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.74 lb, the mean of all of the weights is x = 1.866 lb, and the standard deviation of the weights is s = 2.472 lb.a. What is the difference between the weight of 5.74 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 5.74 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 5.74 lb significant?

A vendor converts the weights on the packages she sends from pounds to kilograms (1 kg ≈ 2.20 lb). The mean weight of the package was 21 lb with standard deviation of 0.31 lb. After repackaging (converting units), the mean becomes kg (round your answer to 2 decimal places), and the standard deviation becomes kg (round your answer to 2 decimal places).
