a) Provide null and alternative hypotheses in formal terms and layperson's terms for the t test for independent samples

b) Do the math and reject/accept at a=.05

c) Explain the results in layperson's terms

d) Calculate and explain a 95% confidence interval in layperson's terms if appropriate. If not, you must explain why not.
