Question 14 1 pts The normal distribution has all of the following characteristics, except that O it is symmetrical its distribution is theoretical the total area under the curve is greater than 1.0 the mean, median, and mode are equal Question 15 1 pts When drawing the normal curve, you can drop a line at the inflection point, which is the point on either side of the mean where the curve changes from concave to convex. That line, when it is on the left side of the mean, represents 0 A), a z-score of-1.0 one standard deviation below the mearn the left boundary of an area between the mean and z of about 34% all of the above

Explanation / Answer

The normal distribution is symmetrical, theoretical and have equal mean, median and mode having total area under the curve equal to 1.

Thus the statement, the total area under the curve is greater than 1.0 is false.

A line dropped at the inflection point of normal distribution curve is one standard deviation away from the mean.

Thus, the line on the left side of the mean represents a Z-score of -1, so the left boundary of an area between the mean and z of about 34%.

Thus, the answer is:

all of the above
