Two teaching assistants, Camille and Julianne, wanted to investigate the the average number of hours students spend on homework each week. The hypotheses they used were: Ho: H< 3.5, Ha: µ > 3.5. Each TA collected a random sample of 50 students and performed the hypothesis test. Camille rejected the null hypothesis based on her sample, and Julianne failed to reject the null hypothesis based on her sample. Suppose the actual average time students spend on homework each week is 3.2 hours. Which of the following is correct? O A. Camille committed no error and Julianne committed a type I error. O B. Camille committed no error and Julianne committed a Type Il error. O C. Camille committed a type I error and Julianne committed no error. D. Camille committed a type I error and Julianne committed a type Il error.
