Answer: A. 5%
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%

The bottom layer of a decision tree provides information on: D. How all the connected factors lead to a final decision or outcome.
<h3>What is a decision tree?</h3>
A decision tree can be defined as a tree-like model that is used by mathematicians (statisticians) or researchers as a decision support tool, so as to graphically display decisions with respect to their potential outcomes, consequences, utility and resource costs.
This ultimately implies that, it is used for making decisions in business management or computer programming by graphically displaying all the possible (expected) outcome of a decision in layers.
In conclusion, the bottom layer of a decision tree provides information on how all the connected factors lead to a final decision or expected outcome.
