Cholesterol Assume the cholesterol levels of adultAmerican women can be described by a Normal modelwith a mean of 188 mg/dL and a standard deviationof 24.a) Draw and label the Normal model.b) What percent of adult women do you expect to havecholesterol levels over 200 mg/dL?c) What percent of adult women do you expect to havecholesterol levels between 150 and 170 mg/dL?d) Estimate the IQR of the cholesterol levels.e) Above what value are the highest 15% of women’scholesterol levels?
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!
Cholesterol Assume the cholesterol levels of adult
American women can be described by a Normal model
with a mean of 188 mg/dL and a standard deviation
of 24.
a) Draw and label the Normal model.
b) What percent of adult women do you expect to have
cholesterol levels over 200 mg/dL?
c) What percent of adult women do you expect to have
cholesterol levels between 150 and 170 mg/dL?
d) Estimate the IQR of the cholesterol levels.
e) Above what value are the highest 15% of women’s
cholesterol levels?
