A random sample of 6 people who went on a diet recorded their weight loss (in pounds) ""x"" after 3 months. The results are as follows: a.) What is the sample Mean $ar{x}$? b.) Fill in the blanks in the table below to help solve for the Standard Deviation of the sample. egin{tabular}{|c|c|c|c|c|} hline x & $(x - ar{x})$ & $(x - ar{x})^2$ & x & $x^2$ \ hline 8 & & & 8 & \ 9 & & & 9 & \ 13 & & & 13 & \ 15 & & & 15 & \ 19 & & & 19 & \ 32 & & & 32 & \ hline end{tabular} c.)
