If 500 high school students, 376 said they would prefer to have computers in every classroom then the confidence interval at 95% is (71.41%,78.99%)  Since option (a) is correct.

Given x= 376, n = 500

The (71.41%,78.99%)  

\hat{p}=\frac{x}{n}\\ =\frac{376}{500} \\=0.752

Critical values

Using the z-table the z-critical value at the given significance level at α=0.05 is,z_{a/2} =1.96

Construct a 95% confidence interval

That is,

\hat{p}= z_{a/2}\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }

  =0.752\pm 1.96\sqrt{\frac{0.752(1-0.752)}{500} }

  =0.752\pm 0.0379

  = (71.41%,78.99%)
