An explanation of the results would greatly appreciated

Compute the expected value & variance. f (t) = BtB-1e(-t)B Assuming a B = 3 f (t) = 3the (-t)3 Now, take your now fully defined function and compute: (i) The expected value E = S t . f(t) dt (ii) The variance VAR = S (t - M)2 . f(t) dt Then record the values for: the mean u = the expected value the standard deviation o = vthe variance
