Determine if the following statement is true or false. the normal curve is symmetric about itsĆ¢ā¬ā¹ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about itsĆ¢ā¬ā¹ mean, because the mean is the balancing point of the graph of the distribution. the median is the point whereĆ¢ā¬ā¹ 50% of the area under the distribution is to the left andĆ¢ā¬ā¹ 50% to the right.Ć¢ā¬ā¹ therefore, the normal curve could only be symmetric about itsĆ¢ā¬ā¹ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with oneĆ¢ā¬ā¹ peak, which means theĆ¢ā¬ā¹ mean, median, and mode are all equal.Ć¢ā¬ā¹ therefore, the normal curve is symmetric about theĆ¢ā¬ā¹ mean, mu. c. the statement is false. the mean is the balancing point for the graph of aĆ¢ā¬ā¹ distribution, andĆ¢ā¬ā¹ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of aĆ¢ā¬ā¹ distribution, andĆ¢ā¬ā¹ therefore, all distributions are symmetric about the mean.
