A square has four 90° angles. So:

15x-30=90 add 30 to both sides

15x=120 divide both sides by 15

x=8°

Suppose the z-score of your grade on this Statistics exam turns out to be z=0.87. Which of the following is the best interpretat

exis [7]

Answer:

c.My grade is 0.87 standard deviations above the mean.

Step-by-step explanation:

given that the z-score of your grade on this Statistics exam turns out to be z=0.87.

Z score is nothing but std normal variate

Any normal distribution can be converted into std normal by the transformation

Z = $\frac{x-\mu}{\sigma}$

Thus when z=0.87 we mean

x = Mean +0.87 sigma

Or my grade is 0.87 std deviations above the mean

Hence option C is right.

c.My grade is 0.87 standard deviations above the mean.
