Mean = (9.1 + 9.2 + 9.3 + 9.3 + 9.5 + 10.4 + 10.5 + 10.6 + 10.6 + 10.7 + 11.1 + 11.1 + 11.4 + 11.8 + 11.9 + 11.9 + 12.4 + 12.7 + 12.9)/19 = 196/19 = 10.3
= A/x +B/(x -2) +C/(x -4)
To find A, multiply the expression by x and evaluate at x=0.
.. A = 24/((-2)*(-4)) = 3
To find B, multiply the expression by x-2 and evaluate at x=2.
.. B = (18*2^2 -68*2 +24)/(2*(2-4)) = -40/-4 = 10
To find C, multiply the expression by x-4 and evaluate at x=4.
.. C = (18*4^2 -68*4 +24)/(4(4 -2)) = 40/8 = 5
The partial fraction decomposition is
.. = 3/x +10/(x -2) +5/(x -4)
