Answer:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
The best answer for this case would be:
C. Poisson distribution
Step-by-step explanation:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
And for this case we want to calculate this probability:
The best answer for this case would be:
C. Poisson distribution

Step-by-step explanation:
<u>Plotting </u><u />
Step 1: determine the y-intercept
- plot the point as the first point on the graph
Step 2: Move 2 units up, and 1 unit left (keep repeating this process until you have reached the limit of the graph)
Step 3: Go to the other side of the graph of the first point (y-intercept)
- move 2 units down, and 1 unit right keep repeating this process until you have reached the limit of the graph)
<em>When you've completed this process, it should look like this:</em>
