In a survey performed at the University, it was found that 38 out of 275 students interviewed believed that race and racism is an important issue. If we want to construct a 90% confidence interval for the true proportion of students who believe that race and racism is an important issue, what would be the margin of error? (express the result in percentage and round to the nearest ténth).
