Step-by-step explanation:w

standard deviation = ( p(1-p) / n)1/2

p= sample proportion= 55%

n= sample size = 900

standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2

= (0.55*0.45 / 900)1/2

= 0.0165

margin of error = critical value*standard deviation

[ from graph critical value = 2]

margin of error = 2*0.0165=0.033
