10.) The mean clotting time of blood is 7,45 seconds with a standard deviation of 3.6 seconds. What is the probability that an individual's clotting time will less than 2 seconds or greater than 12 seconds? Assume a normal distribution. This problem can be solved using technology or the table for the standard normal curve from your text Click here to view page 1 of the table. Click here to view page 2 of the table. The probability is_____+ (Round to four decimal places as needed)
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!
