All the necessary values have been found to calculate the margin of error We have Za 2 1 960 p 0 26 and E 0 05 Substitute these value rounding the result to four decimal places za 2 p 1 p E 1 96 2 0 26 1 0 26 n Since this value represents a sample size a whole number should be used Using the whole number smaller than this value will result in a larger than desired margin of error so the value should be rounded up to the nearest whole number Thus a sample size of should be used to ensure the margin of error of 0 05 is obtained
