In the context of the problem, which of the following interpretations is correct? Choose the correct answer below. O A. At this student's school 99% of all graduate students study between 17.3 and 22.5 hours per week, on average. O B. Graduate students at this student's school study between 17.3 and 22.5 hours per week 99% of all weeks during the year. O C. There is a 99% chance that the average amount of time spent studying for all graduate students at this student's school is between 17.3 and 22.5 hours per week. O D. We are 99% sure that the average amount of time spent studying among graduate students at this student's school is between 17.3 and 22.5 hours per week. O E. Approximately 99% of all random samples of graduate students from this school will give a mean number of hours studied per week between 17.3 and 22.5. Click to select your answer.
