Answer:
b. 0.6592 and 0.7044
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:
A survey of an urban university showed that 750 of 1,100 students sampled attended a home football game during the season. This means that 
90% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

So the correct answer is:
b. 0.6592 and 0.7044
