1 5 pts Which of the following characteristics does not apply to a theoretical normal distribution?
(a)
(b) It is bimodal. (d) 5 pts The mean, median, and mode are equal. (c) 5 It is bellshaped. It is never negative. For a normal distribution curve with a mean of 19 and a standard deviation of 6, which range of the variable
deﬁnes an area under the curve corresponding to a probability of approximately 68%?
(a) from 16 to 22 (b) from 13 to 25 (c) from 19 to 31 (d) from 7 to 31 5 5 pts In a standard normal distribution, what negative z value corresponds to 17% of the data between the mean
and the z value? 6 5 pts The average national SAT score is 1019. If we assume a bellshaped distribution and a standard deviation
equal to 110, what percentage of scores will you expect to fall above 1129? Dr. Emmert Summer 2010 I of I Points Earned of 20 Learning Outcomes
