Use technology to find the indicated area under the standard Normal curve. Include an appropriately labeled sketch of the Normal curve and shade the appropriate region. a. Find the area in a standard Normal curve to the left of 1.32. b. Find the area in a standard Normal curve to the right of 1.32. Remember that the total area under the curve is 1. a. Which graph below shows the area in a standard Normal curve to the left of 1.32? OA. OB. Oc. OD. The area in a standard Normal curve to the left of 1.32 is- (Round to four decimal places as needed.) b. Which graph below shows the area in a standard Normal curve to the right of 1.32? OA. OB. OC. OD. The area in a standard Normal curve to the right of 1.32 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!
