Solution

for accounting midterm, mean score =102 and s.d =14 and Bob got 116
for biology midterm ,mean score = 70 s.d =5 and Bob got 82

for accounting, p(x <= 116) = p( z <= (116-102)/14 )
   = p(z <=1 ) = 0.8413447

so,he did better than 84.13% of the class in accounting.

Now, for biology, p( x<=82) = p(z <= (82-70)/5 ) =p(z<=2.4 )=0.9918025

So,he did better than 99.18% of the class in biology.
SO,it is evident that the biology score is higher with respect to the rest of the class.
