onsider a value to be significantly low if its z score less than or equal to 2 or consider a value to be significantly high if its z score is greater than or equal to 2. A data set lists weights (grams) of a type of coin. Those weights have a mean of 5.37667 g and a standard deviation of 0.06227 g. Identify the weights that are significantly low or significantly high. What weights are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice.

B. Scores that are greater than ____. (Round to five decimal places as needed.)
C. Scores that are between ___ and ___.
(Round to five decimal places as needed. Use ascending order.)

Explanation / Answer

A. For scores that are significantly low, the z score is less than or equal to -2.
z = (x - )/, -2 = (x - 5.37667)/0.06227, x = 5.25213

Scores that are less than 5.25213

B. For scores that are significantly high, the z score is more than or equal to 2.

z = (x - )/, 2 = (x - 5.37667)/0.06227, x = 5.50121

Scores that are greater than 5.50121

C. Scores that are between 5.25213 and 5.50121
