Zach has a z-score of -1.5
What is his height in inches

Multiply the z-score by the standard deviation:
2 x -1.5 = -3
Now add that to the mean:
49 + -3 = 46 inches.
Answer:
Mean = 49 inches
Standard deviation = 2 inches
Z Score for the Distribution = -1.5
Formula for , Z Score
[tex]Z_{score}=\frac{X-\mu}{\sigma}\\\\ -1.5 =\frac{X- 49}{2}\\\\ X-49 = -1.5 \times 2\\\\ X= 49 -3\\\\ X=46[/tex]
So, Height in inches = 46 inch
