Answer:
The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
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:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
72% of Americans said that they had at least one credit card
This means that 
Give the 95% margin of error for this estimate.


The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
