The denominator is always the number under so in this fraction, we can say 23 is the denominator because it is the number under
Scores that are greater than 31 are significantly high.
Scores that are less than 11.4 are significantly low.
The test scores between 11.4 and 31 are not significantly low or significantly high.
<h3>How to Identify significance values?</h3>
We are given;
Standard deviation; s = 4.9
From the complete question, we are told to consider 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.
Thus;
2s = 2 * 4.9 = 9.8
Scores that are greater than 21.2 + 9.8 = 31 are significantly high.
Scores that are less than 21.2 - 9.8 = 11.4 are significantly low.
Thus, the test scores between 11.4 and 31 are not significantly low or significantly high.
