During the last leap year, whose heart beat more times and how many more times did it beat?
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!
Generally speaking, the fewer times your heart beats every minute, the healthier you are, and a longer life span will be more likely. Ben and Sierra compared their heart rates. Sierra had been exercising every day for at least a year. Her heart rate during the 45 minutes each day that she exercised was 150 beats per minute. But her heart rate dropped to 60 beats per minute for the rest of the day. Ben didn’t exercise at all and had a daylong average heart rate of 72 beats per minute. During the last leap year, whose heart beat more times and how many more times did it beat?
