Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
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:
The lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
