(b) Regardless of your answer to part (a), run a t-test for the difference between
the two treatment means at the a =
5% level of significance.
Specifically, we are interested in knowing if there exists sufficient statistical
evidence to support the claim that low temperatures increase blood pressure
in rats. Be sure to state the null and alternative hypotheses, calculate the
appropriate test statistic, calculate the p- value, and state your conclusions.

The alternative hypothesis: Ha : µ1 > µ2
data: bloodpressure26 and bloodpressure5
t = -18.509, df=8.3215, p-value = 2.348e-08
alternative hypothesis: true difference in means is less than 0
