The true population mean of the final exam marks in a course is 80 marks (out of 100 marks). Suppose that the Lecturer in Charge takes a random sample of 100 students that has a sample mean of 82 marks in the final exam. After analyzing the sample, the Lecturer in Charge fails to reject the null hypothesis that the population mean of the final exam marks is equal to 80 marks. We say: Select one: O a. The Lecturer in Charge has made a correct decision. b. The Lecturer in Charge has committed a Type II error. O c. The Lecturer in Charge has committed a Type | error. O d. None of the listed answers is correct. O e. The Lecturer in Charge has committed both Type I and Type II errors
