(e) 2.9867
Step-by-step explanation:
The <em>z</em>-score of a raw score <em>X</em> is a standardized score that follows a normal distribution with mean 0 and standard deviation 1.
The formula to compute the <em>z</em>-score is:
<u>Given</u>:
Mean (<em>μ</em>) = $775
Standard deviation (<em>σ</em>) = $75
(a)
For <em>X</em> = $699 the <em>z</em>-score is:
(b)
For <em>X</em> = $949 the <em>z</em>-score is:
(c)
For <em>X</em> = $625 the <em>z</em>-score is:
(d)
For <em>X</em> = $849 the <em>z</em>-score is:
(e)
For <em>X</em> = $999 the <em>z</em>-score is:
