Now, use the Dogs.csv data set to calculate the mean maximum lifespan of the dog breeds. This program already finds the sum of the column, add the code to calculate the mean, and output the result. The output should have the following format.
The mean lifespan is 13.495238095238095

After traversing and finding the sum, divide it by the size of the column(e.g. column:GetSize()). Then, output the mean. Notice that the sum has changed to a variable with a number type. This was changed to prevent integer division, which would have cut off the decimal.
