A male student of the author has a measured pulse rate of 52 beats per
Liono4ka [1.6K]

Answer:

z=-1.49

Step-by-step explanation:

\text{Standard Score, z} =\dfrac{X-\mu}{\sigma} $ where:\\\\Mean Pulse rate, \mu =67.3$ beats per minute\\Standard Deviation, \sigma =  10.3$ beats per minute.\\

For a male student who has a measured pulse rate of 52 beats per  minute.

Raw Score, X =52 beats per  minute.

Therefore:

\text{Standard Score, z} =\dfrac{52-67.3}{10.3}\\z=-1.49

Since the usual pulse rates are within 2 standard deviations of the mean, a z-score of -1.49 tells us that the selected student's pulse rate is within the usual pulse rates.

The scale factor represents the change between the different sizes. We multiply by it to increase and divide by it to reduce.

1.772 / 1.21 = 1.464
