Question 1:

An experiment was conducted to determine whether giving candy to dining parties resulted in greater tips. The mean tip LL n X S percentages and standard deviations are given in the accompanying table along with the sample sizes. Assume that the No candy H1 29 19.36 1.52 two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b). Two candies H2 29 22.34 2.58 a. Use a 0.01 significance level to test the claim that giving candy does result in greater tips. What are the null and alternative hypotheses? OA. HO: M1 = H2 OB. HO: H1 = H2 H1: My # H2 Hy: My H2 H1: My
