best method to obtain the data for the chosen hypothesis in this study.Confidence Interval/Margin of ErrorFor this study, the researchers selected to use a confidence level of 95%. They alsodetermined that the margin of error is 1.5 percentage points. This confidence interval is veryhigh and indicates that the researchers feel that you can be 95% certain that if you had asked thequestion of the entire relevant population, the outcome would have been the same. Therefore, ifthe researchers were able to interview every American worker, the survey result would be 95%the same as the results from the sample group of 8,360 workers interviewed. Hence, one in fourblack workers feel that they have been discriminated against at work.
