Formula:
Putting values, we get,
Thus, the sample size must be approximately 822 to obtain a 95% confidence interval with an approximate margin of error of 0.03
b) Margin of error for the 95% confidence interval
p = 54% = 0.54
Formula:
Putting values, we get,
The margin of error now will be 0.03407.
