PPT-How can we use the normal distribution curve to find percentages and amounts?

The Standard Deviation percentages can be broken into smaller percentage parts On the 5 th slide you saw the one standard deviation above and below the mean contained 68 of the data Two standard deviations above and below the mean contained 95 of the data . http. ://www.youtube.com/watch?v=xDIyAOBa_yU.

(b) Here is a curve showing the proportion of batting averages above 0.329. Since 0.329 is exactly two standard deviations above the mean, we know that about 95% of batting averages will be between 0.193 and 0.329. Since the curve is symmetric, half of the remaining 5%, or 2.5% should be above 0.329. Learning Targets. This section presents the . standard normal distribution. which has three properties:.

The Normal distribution is by far the most important and useful probability distribution in statistics, with many applications in economics, engineering, astronomy, medicine, error and variation analysis, etc. The Normal distribution is often called the bell curve, due to its distinctive shape..
