Mu = sigma = The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below. A. The z scores are measured with units of "minutes per beat". B. The z scores are measured with units of "beats." C. The z scores are measured with units of seats per minute." D. The z scores are numbers without units of measurement.
