A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.15 lb, the mean of all of the weights is x overbarequals2.186 lb, and the standard deviation of the weights is sequals1.733 lb.
a. What is the difference between the weight of 5.15 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 5.15 lb to a z score.
d. If we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the weight of 5.15 lb significant?
a. What is the difference between the weight of 5.15 lb and the mean of the weights?
Mean of weight is given by 2.186.
The difference between the weight of 5.15 lb and the mean of the weight is
(5.15 - 2.186) lbs = 2.964 lbs.
b. How many standard deviations is that [the difference found in part (a)]?
2.964lbs.
c. Convert the weight of 5.15 lb to a z score?
d. If we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the weight of 5.15 lb significant?
It is between -2 to +2 . Therefore it is neither significantly low nor significantly high, is the weight of 5.15 lbs significant
