A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.31 lb, the mean of all of the weights is x = 2.225 lb, and the standard deviation of the weights is s= 1.822 lb. a. What is the difference between the weight of 5.31 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 5.31 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 5.31 lb significant? a. The difference is lb. (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.

Question
![A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.31 lb, the mean of all of the weights is \( \bar{x} = 2.225 \) lb, and the standard deviation of the weights is \( s = 1.822 \) lb.
a. What is the difference between the weight of 5.31 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 5.31 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 5.31 lb significant?
---
a. The difference is \(\_\_\_\) lb.
(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 \(\_\_\_\_\_\).
(Choose whether the weight is significantly high, significantly low, or neither.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fecccc45a-2b97-4a81-a445-917c051abee8%2F6217049c-6876-4096-a1bb-1dddf516abf4%2Fcj88e7_processed.png&w=3840&q=75)
