Determine if the following statement is true or false. the normal curve is symmetric about itsΓ’β¬βΉ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about itsΓ’β¬βΉ mean, because the mean is the balancing point of the graph of the distribution. the median is the point whereΓ’β¬βΉ 50% of the area under the distribution is to the left andΓ’β¬βΉ 50% to the right.Γ’β¬βΉ therefore, the normal curve could only be symmetric about itsΓ’β¬βΉ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with oneΓ’β¬βΉ peak, which means theΓ’β¬βΉ mean, median, and mode are all equal.Γ’β¬βΉ therefore, the normal curve is symmetric about theΓ’β¬βΉ mean, mu. c. the statement is false. the mean is the balancing point for the graph of aΓ’β¬βΉ distribution, andΓ’β¬βΉ 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 aΓ’β¬βΉ distribution, andΓ’β¬βΉ therefore, all distributions are symmetric about the mean.
