Assume that females have pulse rates that are normally distributed with a mean of μ = 72.0 beats per minute and a standard deviation of σ equals 12.5 beats per minute. Complete parts (a) through (c) below. a- a. If 1 adult female is randomly selected, find the probability that her pulse rate is between 68 beats per minute and 76 beats per minute. The probability is____ b- If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean between 68 beats per minute and 76 beats per minute. The probability is ___
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!
