Expert Solution

Solution,

Given that,

=  1 - = 0.5 ( no prior estimate )

margin of error = E = 0.0254

At 90% confidence level

= 1 - 90%  

= 1 - 0.90 =0.10

/2 = 0.05

Z/2 = Z0.05  = 1.645

sample size = n = (Z / 2 / E )2 * * (1 - )

= (1.645 / 0.0254)2 * 0.5 * 0.5

= 1048.58

sample size = n = 1049
