Well the mean is just the average of all the numbers so all you have to do is add them all up and divide by 9 because there are nine numbers in the sequence and I find it hard to explain how to find standard deviation with out the person in front of me so I found you a website and it goes step by step through the process: https://www.mathsisfun.com/data/standard-deviation-formulas.html
