Answer 1

For the data set weights, The total number of observations is n=8. IM Exi = 1598, IN Xi = 320 166. I - 1598 - 199.75. 1598 - = 199.75 : SX Sn= -3 (0-) -X)? n-1 in - ny

{ 320166- (8-1) 8x1199.75²3 - 11. 744. : CV weights = Sx x 100% 11 744 x 199.75 100% = 5.9%

. For the data set ages, The total number of observations is m=8. S yi - 209, 5507. 121 209 - 26.125.

m -1 12 rüy! migns - Te { 5507 - 8x(+26.125) = 2.588. - CVanes v 100 1. 2. 588 - X100% 26.125

= 9.9 %. We know that if cv of one data set is greater than the ev of another data set, then the variability of that data set (whose cv is Larger) is higher than the variability of the other data set. Here CVages > eV weights : Ages are more varable than weights for all munning backs on this team. option Jis connect.
