The histogram shows the selfreported number of exercise hours in a week for 50 students. Without doing calculations, what is the approximate mean number of exercise hours for these 50 students? Explain. Frequency 18- 16- 14- 12- 10- 0 2 4 6 8 10 12 14 16 18 20 Exercise Hours (per week) Choose the correct answer below. OA. The mean is between about 4 and 6 hours. It is near the center because the distribution is roughly symmetric. B. The mean is between about 4 and 6 hours. It is to the right of the peak because the distribution is skewed right. O C. The mean is between about 6 and 8 hours. The distribution is symmetric, so the mean should be about in the middle. OD. The mean is between about 2 and 4 hours. It is near the center because the distribution is roughly symmetric.
