What are the values of the mean and standard deviation after converting?

Example:Pulse rates of women are normally distributed with a mean of 77.5beats per minute and a standard deviation of 11.6 beats per minute.a) What are the values of the mean and standard deviation afterconverting all pulse rates of women to z-scores usingz=(x−μ)/σ?µ = 0;σ= 1b) The original pulse rates are measured with units of “beats perminute.” What are the units of the corresponding z-scores?The z-scores are numbers without units of measurement.

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
