Question
According to the Energy Information Administration (official energy statistics from the U.S. government), the
mean price for one gallon of unleaded regular gasoline in U.S. cities for August, 2011 was $3.64. A random
sample of 30 pumps in cities in the state of Georgia yielded an average price of $3.16 per gallon for
unleaded gasoline. Assume that o = $0.90. Test whether the population mean price for unleaded gasoline is
lower in Georgia than the general population, using a significance level of a = 0.01.
Select one:
a. p-value = 0.0017, reject Ho.
b. p-value= 0.0036, reject Ho.
c. p-value = 0.4602, do not reject Ho.
d. p-value = 0.0018, do not reject Ho.
