# Question

A study of water use in Gainesville, Florida, indicated that in 2006 residential water consumption had a mean of 78 and a standard deviation of 119, in thousands of gallons.
a. If the distribution of water consumption were approximately normal, then what proportion of the residences used less than 100,000 gallons in 2006? (Assume negative infinity to 100 in calculating the proportion.)
b. In fact, the distribution of water use was not actually normal. What shape do you expect the distribution to have? Why?
