b. have values between -1 and +1.
c. have only negative values.
d. We cannot say what the values on that axis would be.

Question 2

The difference between the histogram of 175 behavior problem scores and a normal distribution is

b. the normal distribution is symmetric, while behavior problem scores may not be.
c. the ordinate of the normal distribution is density, the ordinate for behavior problems is frequency.
d. Each of the previous choices is correct.
