Select the outlier in the data set. 20, 30, 40, 45, 49, 54, 56, 62, 477

Identify Outlier: Identify the data set and look for any numbers that appear to be significantly different from the others. Data set: 20, 30, 40, 45, 49, 54, 56, 62, 477 Looking at the data set, we can see that the number 477 is much larger than the rest of the numbers.Confirm Outlier: To confirm the outlier, we can calculate the mean and standard deviation of the data set and see if 477 falls far outside the range of the other numbers. However, in this case, since 477 is significantly higher than all other values and the rest of the values are relatively close to each other, we can conclude that 477 is the outlier without further calculations.
