1. a)What is your null hypothesis regarding sepal lengths forthe two species? And what is your alternate hypothesis?
b) Describe your hypotheses in terms of your test statistic: whatwould be the t under the null hypothesis, H0, and whatwould be the statement about t under your alternate hypothesisHa? Would you do a one- or non-(i.e.,two-sided) directional test? Why?
