Question

question 2
three students are asked to interpret the meaning of a z - score of 0.
amanda says the value is located at the mean.
brandon says the area to the right of the z - score is 0.0.
charles says the area to the left of the z - score is 0.0.
who is correct?
charles
all three are correct
amanda
brandon

Explanation:

The z - score represents the number of standard deviations a data - point is from the mean. A z - score of 0 means the data - point is at the mean. The area to the left of a z - score of 0 in a standard normal distribution is 0.5, and the area to the right is also 0.5. So only Amanda is correct in her interpretation.

Answer:

C. Amanda
