Step-by-step explanation:
Given : The chance that they will join the graduate program : p=0.10
The total number of students in the class: n = 400
For this binomial situation :
We assume that this is normal distribution.
Let X be the random variable that represents the students will be joining a graduate program.
Z-score :
For x= 50 , we have
Using the standard normal distribution table , we have
Hence, the value i.e.closest to the probability that at least 50 students will be joining a graduate program = 5%
