I will do the first one. Put into a calculator by STAT EDIT and put them into L1 by adding the number and pushing ENTER.
Once they are all entered, push STAT then CALC then 1 1-VAR STATS
x bar x with a line over it is the mean or 52.35294118, round to 52.3
sigma x (the circle with a line on top, below Sx is the standard deviation of the population or 12.753 or 12.8.
Do the others the same way
