Question
A) Resting pulse rate:
Take your resting pulse rate and write it down. According to the NHE, the adult population has a mean resting pulse rate of 72.90 with a standard deviation of 12.30. Using this information and your resting pulse rate, calculate the z score for your pulse rate.
*** My pulse: X = 83 ***
Post your resting pulse rate and the z-score you calculated for it and interpret the z-score (what does it tell you in comparison to others?).
B) Height: What is your height in inches? If you don't know it accurately, stand at a doorway and have someone measure it for you. It is known that for men, the population height is 70 inches with a standard deviation of 4 inches. For women, the population height is 65 inches with a standard deviation of 3.5 inches. Using this information and your height in inches, calculate your z-score for your gender.
Post your height and the z-score you calculated for it and interpret the z-score (what does it tell you in comparison to others?).
*** My height: X = 62 in. ***
Explanation / Answer
A. Z score is defined as (x-mean)/STD Dev
Thus z is (83-72.9)/12.3= 0.82. this means that the weight is 0.82 standard deviations above the mean of 72.9
B. Z score if I am a male is (62-70)/4 or -2
That means that my height is two standard deviations lesser than the mean height
