Solution :
Here the probability that exactly 28 out of 304 students will not graduate on time. That is
P (x = 28)
By using the normal approximation of binomial probability,
∴
That is the area between 27.5 and 28.5
Therefore, the correct option is (e). Area between 27.5 and 28.5
I could be wrong but I got 28. I devided 420 by 15
