? Question 1 10 out of 10 points
The normal curve reaches the horizontal axis in 4 standard deviations above and below the mean.
? Question 2 10 out of 10 points
The area beyond a z score of +2.58 is 0.005.
? Question 3 10 out of 10 points
All standard scores are z scores.
? Question 4 10 out of 10 points
If the original raw score distribution has a mean that is not equal to zero, the mean of the z transformed scores will not equal zero either.
? Question 5 10 out of 10 points
If the original raw score distribution is not normally distributed, the mean of the z transformation scores of the raw data will not equal 0.
? Question 6 10 out of 10 points
It is impossible to have a z score of 30.2.
? Question 7 10 out of 10 points
One cannot reasonably do z transformations on ratio data.
? Question 8 10 out of 10 points
The z distribution takes on the same shape as the raw scores.
? Question 9 10 out of 10 points
A z distribution always is normally shaped.
? Question 10
10 out of 10 points
If the raw score distribution is very positively skewed, the standard deviation of the z transformed scores will not equal 1.
