Use the data set in Table A.1 to test the null hypothesis that the average minimum temperatures for Ithaca and Canandaigua in January 1987 are equal. Compute p values, assuming the Gaussian distribution is an adequate approximation to the null distribution of the test statistic, and

a. H_A
= the minimum temperatures are different for the two locations.

b. H_A
= the Canandaigua minimum temperatures are warmer.
