In the latest National Health and Nutrition Examination Survey (NHANES 2013/2014 – wwwn.cdc.gov/nchs/nhanes), pulse rate (30 sec rate multiplied by 2) of 2536 U.S. adults averaged 71.6 beats/min with a standard deviation of 11.5 beats/min. (Data in NHANES)
a) Can you apply the Central Limit Theorem to describe the distribution of the pulse rates? Why or why not?
b) Can you apply the Central Limit Theorem to describe the sampling distribution model for the sample mean pulse rates of U.S. adults? Why or why not?
c) Sketch and clearly label the sampling model of the mean pulse rates of samples of size 2536 based on the 68-95-99.7 Rule.
