A Fitbit tracks the number of steps that a local professor takes each day. Over one recent six-day period, the professor took the following number of steps: 6200, 6400, 7000, 7000, 8470, and 10500. Note that the median number of steps on these six days is 7000 and the mean number of steps is 7595. On the seventh day, the professor takes more than 12000 steps. How does the median and mean number of steps for the seven days compare to the mean and median for the initial six days? The median number of steps for the seven days is GREATER than the median for the initial six days, while the mean number of steps for the seven days is LESS than the mean for the initial six days. The median number of steps for the seven days is LESS than the median for the initial six days, while the mean number of steps for the seven days is GREATER than the mean for the initial six days. The median number of steps for the seven days EQUALS the median for the initial six days, while the mean number of steps for the seven days is GREATER than the mean for the initial six days. The median number of steps for the seven days EQUALS the median for the initial six days, while the mean number of steps for the seven days is LESS than the mean for the initial six days
