Using the z-distribution, it is found that a sample size of 1066 is required.
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 z-score that has a p-value of .
The margin of error is:
From the previous study, the estimate is of 0.23, hence .
98% confidence level, hence, z is the value of Z that has a p-value of
, so
.
The sample size is <u>n for which M = 0.03</u>, hence:
Rounding up, a sample size of 1066 is required.
