B: Scores below the top 5% and above the bottom 62%
We have to find the value of x such that the probability is 0.62
Calculation the value from standard normal z table, we have,
We have to find the value of x such that the probability is 0.05

Calculation the value from standard normal z table, we have,
Thus, the numerical value of score to achieve grade B is
