Use y <->

(a) Calculate the mean and standard deviation of y.

(b) Use a loop to repeat the above calculation 25 times. Store the 25 means in a vector named av. Calculate the standard deviation of the values in av.

(c) Create a function that performs the calculations described in (b). Run the function several times, showing each of the distributions of 25 means in a density plot.
