Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: <em>$95 + $55 = $150</em>
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: <em>There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55. </em>
c. What is the total cost for x months? (Write an equation for the situation.)

Answer:
The standard deviation of the distribution is 21.7 students.
Step-by-step explanation:
We are given the following in the question:
We treat college student living on campus as a success.
P(college student living on campus) = 0.38
Then the number of students follows a binomial distribution.
Sample size, n = 2000
We have to evaluate the standard deviation of the distribution.
Formula:

Putting values, we get,

Thus, the standard deviation of the distribution is 21.7 students.
