Hypothesis Testing - Setup: Suppose you want to test the claim that the mean volume in all 12-ounce cans of Fizzy Pop soda is greater than 12 ounces. In a sample of 120 cans, you find the sample mean is 12.3 ounces. (a) What is the claim? 0 д< 12 Ο 0 Ο μ > 12 м = 12 Ο 0 Ο μ = 12.3 (b) What does μ represent? the mean volume of all 120 cans from the sample the mean volume of all 12-ounce cans of Fizzy Pop the proportion of all cans with a volume > 12 ounces (c) What is the null hypothesis? μ < 12 Д> 12 μ = 12 0 H = 12.3 (d) What is the alternate hypothesis? 0 με 12 Ο μ > 12 од + 12 Ο μ = 12.3 (d) What type of test is this? Oleft-tailed Oright-tailed Otwo-tailed
