22 32 42 52 62 72 First, we note that 42 is By the Empirical Rule, below. For the graph shown above, we will use the Empirical Rule to find the percentage of values less than 42. 22 32 42 22 Thus we know that 32 42 82 92 102 a standard deviations below the mean of 62. Let's explore some more. % of values are within two standard deviations of the mean, as shown 52 62 72 82 92 102 % of values are between 42 and 62, as shown below. We also know that 50% of values are less than 62. So therefore, % of values must be less than 42. 52 62 72 82 92 102 By symmetry, we can see that the percent of values above below. would also be 2.5%, as shown
Thus we know 22 32 42 52 62 72 82 22 We also know that 50% of values are less than 62. So therefore, of values must be less than 42. Let's explore some more. By symmetry, we can see that the percent of values above below. Thus alues are between 42 and 62, as shown be w. 32 42 52 62 72 82 92 102 percent of values are less than 82, as shown below. 42 52 62 92 102 Q Submit Question 72 In other words, the value 82 would be the 82 92 102 Q th percentile. would also be 2.5%, as shown
