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.
