0 Question 9 v For the graph shown above, we will use the Empirical Rule to find the percentage of values less than 41. First, we note that 41 is standard deviations below the mean of 57. By the Empirical Rule, % of values are within two standard deviations of the mean, as shown below. 81 89 Thus we know that 96 of values are between 41 and 57, as shown below. We also know that 50% of values are less than 57. So therefore, 96 of values must be Less than 41. Let's explore some more. By symmetry. we can see that the percent of values above Thus percent of values are less than 73, as shown below. would also be 2.5%, as shown below. + 49 81 25 41 57 65 73 89 33 Q In other words, the value 73 would be the th percentile
