<h2><u>COMBINED OPERATIONS</u></h2><h3>Exercise</h3>
First, let's solve the subtraction (in parentheses):


Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:


Finally, let's solve the division:

<h3><u>Answer</u>: 16</h3>
Answer:
a) n = 1037.
b) n = 1026.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of 
The margin of error is:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
(a) Assume that nothing is known about the percentage to be estimated.
We need to find n when M = 0.04.
We dont know the percentage to be estimated, so we use
, which is when we are going to need the largest sample size.






Rounding up
n = 1037.
(b) Assume prior studies have shown that about 55% of full-time students earn bachelor's degrees in four years or less.

So






Rounding up
n = 1026.
