Select the correct choice below and fill inthe answer box within your choice.(Type an integer or a decimal. Do not round.)A. The marketing department committed a Type Il error because the marketing department did not reject the alternative hypothesis when the null hypothesis wastrue. The probability of making a Type Il error isB. The marketing department committed a Type I error because the marketing department rejected the null hypothesis when it was true. The probability ofmaking a Type I error isC. The marketing department committed a Type I error because the marketing department did not reject the alternative hypothesis when the null hypothesis wastrue. The probability of making a Type I error isD. The marketing department committed a Type Il error because the marketing department rejected the null hypothesis when it was true. The probability ofmaking a Type Il error is.Best
