Given:
Mean, μ = 95
Standard deviation, σ = 10
Let's find the test score 1.5 standard deviations below the mean.
To find the test score, apply the formula:
[tex]X=\mu-1.5\sigma[/tex]Thus, we have:
[tex]\begin{gathered} X=95-1.5(10) \\ \\ X=95-15 \\ \\ X=80 \end{gathered}[/tex]Therefore, the test score 1.5 standard deviations below the mean is 80 .
• ANSWER:
80
