ElenaW [278]

Answer:   The margin of error = 3\%

Step-by-step explanation:

Given

Sample size (n) = 1000

Population proportion = 0.4

\alpha = 1 - confidence level

  = 1 - 0.95

   = 0.05

margin\;  of\;  error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{p}}{(1 -\widehat{p})}}{n}}

margin\;  of\;  error = z_{\frac{0.05 }{2}\sqrt{\frac{{(0.4)}{(1 -0.4)}}{1000}}

                             = z_{0.025}\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}

                             = 1.96\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}

                            =  0.03

The margin of error change to 2.5\% to 3\%
