A random sample of 97 cans of coke were observed and yeilded a mean of 353.3 mL and a standard deviation of 1.75 mL. Coke says that the population mean of their cans is 355 mL. Do we have enough evidence to show that the mean is not 355 mL? Use a = 0.05 and use our tables.

Question
A random sample of 97 cans of coke were observed and yeilded a mean of 353.3 mL and a standard deviation of 1.75 mL. Coke says that the population mean of their cans is 355 mL. Do we have enough evidence to show that the mean is not 355 mL? Use a = 0.05 and use our tables. Select the correct null and alternative hypotheses: OA. Ho X = 353.3,H₁ : X ‡ 353.3 Ο Β. Η : μ = 355,HA : μ < 355 OC. Ho μ = 355,H₁ : μ355 OD. Ho μ = 355,H₁ μ> 355 OE. Ho: X = 353.3,HA: X < 353.3 OF. Ho X = 353.3,HA: X > 353.3 OG. None of the above : Select the type of distribution to be used in this question: OA. Z-distribution OB. t-distribution OC. Chi-Square distribution OD. None of the above The rejection region for this test is: OA. (-∞, -2.575) OB. (-∞, -1.96) OC. (1.96, ∞) OD. (1.645, ∞) OE. (-∞, -1.96) U (1.96,∞) OF. (2.575, ∞) OG. (-∞, -2.575) U (2.575, ∞o) OH.
