Answer:
The margin of error is of 0.038 = 3.8%.
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
.
For this problem, we have that:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The margin of error is:



The margin of error is of 0.038 = 3.8%.
Answer:
952.61
Step-by-step explanation:
877.98 X 0.085= 74.6283
877.98+74.6283=952.6083
952.6083 rouned= 952.61
