Which of the following is NOT a characteristic of the standard normal distribution?Select one:a.50% of all values are negative.b.97.5% of all values are greater than -2c.The mean, median and mode are all equal.d.47.5% of all values lie between -1 and 2.

Which of the following statements is true?Group of answer choicesA. When the distribution is skewed to the left, mean > median > mode.B. When the distribution is skewed to the right, mean < median < mode.C. When the distribution is symmetric and unimodal, mean = median = mode.D.
