Assume that gas prices are normally distributed. Using a 0.01 level of significance, test the claim that the price on November 1 is higher than the price on October 25. Show all your work including the original claim, hypotheses, test statistic, a sketch of the sampling distribution and the -value. State your decision and interpret it in the context of the original claim.
