The Energy Information Administration reported that the mean retail price per gallon of regular grade gasoline was $$3\mathrm{.}43($Energy Information Administration, July $2012).$Suppose that the standard deviation was $$\mathrm{.}10$ and that the retail price per gallon has a bell$-$shaped distribution. What percentage of regular grade gasoline sold for more than $$3\mathrm{.}63$ per gallon?If I use the picture below to solve, would the correct answer be $2\mathrm{.}35\%?$ Because $3\mathrm{.}63$ per gallon is two standard deviations away.

Interpreting Standard Deviation: Empirical Rule (68-95 - 99.7 Rule) -99.7% within 3 standard deviations -95% within 2 standard deviations- 68% within 1 standard deviation 2.35% 13.5% x-3s x-2s 34% 34% 2.35% 13.5% x + s x + 2s x+3s
