The table lists means and standard deviations. The mean is the number before the plus/minus, and the standard deviation is the number after the plus/minus. The results are from a study attempting to find the average blood pressure of older adults. Use the results to answer the questions. Normotensive Hypertensive Men (n Women (n = Men (n: Women (n !! %3D 1200) 1400) 1100) 1300) Age 55 10 55 10 60 ± 10 64 10 Blood pressure (mm Hg) Systolic 123 9 121 11 153 17 156 20 Diastolic 78 7 76 7 91 10 88 10 1. Apply Chebyshev's theorem to the systolic blood pressure of normotensive men. At least how many of the men in the study fall within 1 standard deviation of the mean? 2. At least how many of those men in the study fall within 2 standard deviations of the mean? Assume the blood nressure
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

1) Apply chebyshev's theorem to the systolic blood pressure of normentetive men. Atleast how many of the men in the study fall within 1 standard deviation of the mean?
2) Atleast how many of those men in the study fall within 2 standard deviation of the mean?
Assume the blood pressure is normally distributed among older adults. Answer the following questions using the emperical rule instead of the chebyshev's theorem.
1) What are the ranges for the diatolic blood pressure ( normentetive and hypertensive) of older women?
2) Do the normentetive, make and systolic blood pressure ranges overlap with the hypertensive, male, systolic blood pressure ranges?
