US GDP

Consider the following dataset , which contsins the domestic US gross in millions of the top grossing movie over the last 5 years. 300,452,513,550,780

I. Find the Mean of the Dataset
II. Find the Squared deviation of the second observation from the mean
III. Find the squared deviation of X2 from the Mean

Result

m =  519
d =  4489
x2 =  30392

Solution:
