A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.50 lb, the mean of all of the weights is x= 2.240 Ib, and the standard deviation of the weights is s= 1.134 Ib. a. What is the difference between the weight of 5.56 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 5.50 lb to az score. d. If we consider weights that convert to z scores between - 2 and 2 to be neither significantily low nor significantly high, is the weight of 5.50 Ib significant? a. The difference is O 16. (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal places as needed.) o. The z score is z (Round to two decimal places as needed.) d. The highest weight is

A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.56 Ib, the mean of all of the weights
is x= 2.248 Ib, and the standard deviation of the weights is s= 1.134 Ib.
a. What is the difference between the weight of 5.56 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 5.56 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 5.56 Ib significant?
a. The difference is Ib.
(Type an integer or a decimal. Do not round.)
b. The difference is
standard deviations.
(Round to two decimal places as needed.)
c. The z score is z=.
(Round to two decimal places as needed.)
d. The highest weight is
