1. 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 120 cans, you find the sample mean is 12.2 ounces. (a) What is the claim? μ < 12 μ > 12 μ = 12 μ = 12.2 (b) What does μ represent? the proportion of all cans with a volume = 12 ounces the mean volume of...
Example 2.13 Perform the following hypothesis tests of the population mean. In each case, draw a picture to illustrate the rejection regions on both the Z and X distributions, and calculate the p-value of the test. Ho: μ-25, H,: μ < 25, n . 100, X 24, σ 5, α 0.1
please help me set this up correctly
i am confused as to which formulas to use. pictures and step by
step work will help. thank you.

if answered correctly and neatly i will thumbs up!! please
answer all thank you!

Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 − α confidence...
