A random sample of 15 college students were asked "How many hours per week typically do you work outside the home?" Their responses are shown on the 14 right. 13 Determine the shape of the distribution of hours worked by drawing a frequency histogram and computing the mean and median. Which measure of central tendency better describes hours worked? Choose the correct frequency histogram below. O A.
