Q. Select the outlier in the data set.8,75,81,85,88,89,94,96,97
Identify Outlier: To identify the outlier in the data set, we first need to look at the numbers and see if there is a number that is significantly different from the others. Looking at the data set: 8,75,81,85,88,89,94,96,97, we can see that the number 8 is much smaller than all the other numbers, which are all 75 or higher.
Confirm Outlier: To confirm that 8 is an outlier, we can calculate the mean and standard deviation of the data set and then determine if 8 falls far outside the range of the other values. However, in this case, since 8 is so much smaller than the other numbers and the rest of the numbers are relatively close to each other, we can reasonably conclude that 8 is the outlier without further calculations.
