29.The standard deviation of the sample means is equal to which of the following?  A. population standard deviation divided by the square root of n (sample size)  B. sample standard deviation divided by n (sample size)  C. sample standard deviation divided by the square root of n (sample size)  D. population standard deviation divided by n (sample size)

The variance is:a. The square root of the sum of squared deviations from the meanb. The average of squared deviations from the meanc. The average of absolute deviations from the meand. The square of the standard deviation

Which of the following statements is true?Group of answer choicesThe sum of the deviations from each value in a data set to the mean, is always zero.The sum of the squared deviations from the mean is always zero.The standard deviation is in squared units.The standard deviation is always greater than the variance.
