Question 1204120



The sample size ({{{n }}}) is calculated according to the formula: 

{{{n = z^2 * p * ((1 - p) / e^2 )}}}

Where: {{{z = 2.326 }}} for a confidence level (α) of {{{98%, {{{p }}} = proportion (expressed as a decimal), {{{e }}} = margin of error.


given:

{{{z = 2.326 }}}, {{{p = 0.48 }}}, {{{e = 0.05 }}}


{{{n = 2.326^2 * 0.48 * ((1 - 0.48) / 0.05^2 )}}}


{{{n = 1.3504048896 / 0.0025  }}}


{{{n= 540.16195584 }}}


The sample size is equal to {{{540 }}}
