In the table below x denotes the X-Tract Company’s projected annual profit (in $1,000).  The table also shows the probability of earning that profit.  The negative value indicates a loss.   x f(x)   x = profit   -100 0.01   f(x) = probability -200 0.04       0         100 0.26       200 0.54       300 0.05       400 0.02         14 If we quadruple each value in the profit column above, the new variance of profit will be. a 187,136               b 183,467               c 179,870               d 46,784
