It is claimed that the average sale at Starbucks is eleven dollars. A random sample of 20 transactions were observed and yeilded a mean of 10.39 dollars. Assuming that o = 2.61 dollars, do we have enough evidence to show that the mean is less than eleven dollars? Use a = 0.01 and use our tables. Select the correct null and alternative hypotheses: OA. Ho: X 10.39,HA: X < 10.39 Ο B. Ho : μ = 11,HA : μ > 11 OC. Ho: p= 11,HA: 11 OD. Ho: X = 10.39,HA X> 10.39 OE. Ho: X = 10.39,HA: X Ο F. Ho : μ = 11,HA : μ < 11 OG. None of the above 10.39 Select the type of distribution to be used in this question: OA. t-distribution OB. Z-distribution OC. Chi-Square distribution D. None of the above The rejection region for this test is: OA. (-∞, -1.645) OB. (2.575, ∞) OC. (1.645, ∞) OD. (-∞, -2.575) U (2.575, ∞) OE. (-∞, -2.575) OF. (2.33, ∞) OG. (-∞, -2.33) OH.
