Question
A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.47 Ib, the mean of all of the weights is x = 1.819 Ib, and the standard deviation of the weights is s =1.401 lb.
a. What is the difference between the weight of 5.47 Ib and the mean of the weights?
b. How many standard deviations is that [the difference found in part (a)]?
c. Convert the weight of 5.47 Ib 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 5.47 Ib significant?
a. The difference is Ib.
(Type an integer or a decimal. Do not round.)
