Hypothesis Testing - Setup: Suppose you want to test the claim that the mean volume in all 12-ounce cans of Fizzy Pop soda is equal to 12 ounces. In a sample of 80 cans, you find the sample mean is 12.2 ounces. (a) What is the claim? _? < 12 _? > 12 _ ? = 12 _? = 12.2 (b) What does ? represent? _the mean volume of all 12-ounce cans of Fizzy Pop the proportion of all cans with a volume = 12 ounces the mean volume of all 80 cans from the sample (c) What is the null hypothesis? _? < 12 _? > 12 _ ? = 12 _? = 12.2 (d) What is the alternate hypothesis? ? < 12 ? > 12 ? ? 12 ? = 12.2 (d) What type of test is this? _left-tailed _right-tailed two-tailed
