the table to answer tne question. Note: Round z-scores to the hearest hundreath and the required A values using the table. The cholesterol levels of a group of young women at a university are normally distributed, with a mean of 182 and a standard deviation of 37. What percent of the young women have the following cholesterol levels? (Round your answers to one decimal place.) (a) greater than 220 % (b) between 186 and 224
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!
