|---|---|---|---|---|---|---|
| Lafayette | 3.599 | 3.379 | 3.199 | 3.199 | 3.549 | 3.349 |
(a) Find the mean price in each city. (Round your answers to three decimal places.)
| Novato | $ |
| Lafayette | $ |
Which city has the lowest mean?
NovatoLafayette
(b) Find the standard deviation of prices in each city. (Round your
answers to three decimal places.)
| Novato | $ |
| Lafayette | $ |
(c) Which city has more consistently priced gasoline? Why?
The gas in Lafayette is more consistently priced because it has a smaller mean.The gas in Lafayette is more consistently priced because it has a smaller standard deviation. The gas in Novato is more consistently priced because it has a smaller mean.The gas in Novato is more consistently priced because it has a smaller standard deviation.
