Which is true?<br> will mark you as brainliest:))

Answer: A.

Step-by-step explanation:

To find mean, average the numbers in the data set by adding them together and dividing by the number of values.

(96 + 77 + 82 + 91 + 89) / 5 = 87.

To find median, take the "middle" value of the data set. To find this, you can sort the numbers in ascending order and remove the same amount of values from each side.

77 / 82 / 89 / 91 / 96, the median is 89.

Therefore, the mean is less than the median.

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.
