If you are interested in identifying children who are highly aggressive, and you have a normally distributed scale that will do so, you will be particularly interested in
 
  a. scores on that scale that are substantially above the mean.
  b. scores on that scale that are substantially far from the mean.
  c. scores on that scale that are substantially below the mean.
  d. any extreme score.

Question 2

The tables of the standard normal distribution contain only positive values of z. This is because
 
  a. the distribution is symmetric.
  b. z can take on only positive values.
  c. we aren't interested in negative values of z.
  d. probabilities can never be negative.

Question 3

If behavior problem scores are roughly normally distributed in the population, a sample of behavior problem scores will
 
  a. be normally distributed with any size sample.
  b. more closely resemble a normal distribution as the sample size increases.
  c. have a mean of 0 and a standard deviation of 1.
  d. be negatively skewed.
