Which of the following is not true?

Question

A. A z-score is an area under the normal curve B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution. C. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution. D. If values are converted to standard z-scores, then procedures for working with all normal distributions are the same as those for the standard normal distribution.

Answer 1

 

The best answer is A.

 

A z-score is not the area under a normal curve.

Answer 2

The best answer is B.

 

 

The z-score standardizes an value from a normal distribution to a standard normal distribution that has a mean of zero and a standard deviation of 1.
