In a normal distribution, which is greater, the mean or the median? a. mean b. median c. neither (they are equal) d. cannot be determined with the information provided.

Choice C) neither (they are equal)

If mean > median, then the distribution would be skewed to the right. 
If mean < median, then the distribution would be skewed to the left. 

However, the normal distribution is not skewed since the normal distribution is symmetric. 
The left side is a mirror image of the right side (or vice versa).
The mean and median are located at the same spot: at the center of the bell curve.
Which is why mean = median

The answer is 225 miles per 4.5 hours. hope this ; )

(6,0) i hope it makes enough sense
