Can you help? The instructor said to use the population standard deviation. And the rest of the questions asked to compute the mean of the Z-scores. The mean of the z-scores is? Compute the standard deviation of the z scoresThe standard deviation of the z-scores is?

The accompanying data represent the pulse rates (beats per minute) of nine students. Treat the nine students as a population. Compute the z-scores for all the students.
