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.
