The price drivers pay for gasoline often varies a great deal across regions throughout the United States. The following data show the price per gallon for regular gasoline for a random sample of gasoline service stations for three major brands of gasoline (Shell, BP, and Marathon) located in 11 metropolitan areas across the upper Midwest region.

Metropolitan Area Shell BP Marathon
Akron, Ohio 3.77 3.83 3.78
Cincinnati, Ohio 3.72 3.83 3.87
Cleveland, Ohio 3.87 3.85 3.89
Columbus, Ohio 3.76 3.77 3.79
Ft. Wayne, Indiana 3.83 3.84 3.87
Indianapolis, Indiana 3.85 3.84 3.87
Lansing, Michigan 3.93 4.04 3.99
Lexington, Kentucky 3.79 3.78 3.79
Louisville, Kentucky 3.78 3.84 3.79
Muncie, Indiana 3.81 3.84 3.83
Toledo, Ohio 3.69 3.83 3.86

Use= 0.05 to test for any significant difference in the mean price of gasoline for the three brands.

State the null and alternative hypotheses.

  1. H0: At least two of the population means are equal. Ha: At least two of the population means are different.
  2. H0:Shell=BP=Marathon Ha:ShellBPMarathon
  3. H0: Not all the population means are equal. Ha:Shell=BP=Marathon
  4. H0:Shell=BP=Marathon Ha: Not all the population means are equal.
  5. H0:ShellBPMarathon Ha:Shell=BP=Marathon

Find the value of the test statistic. (Round your answer to two decimal places.)

Find thep-value. (Round your answer to three decimal places.)

p-value =

State your conclusion.

  • RejectH0. There is not sufficient evidence to conclude that there is a significant difference in the mean price per gallon for regular gasoline among the three brands.
  • RejectH0. There is sufficient evidence to conclude that there is a significant difference in the mean price per gallon for regular gasoline among the three brands.
  • Do not rejectH0. There is not sufficient evidence to conclude that there is a significant difference in the mean price per gallon for regular gasoline among the three brands.
