A consumer research organization states that the mean caffeine content per 12-ounce bottle of a population of caffeinated soft drinks is 37.8 milligrams. You find a random sample of 48 12-ounce bottles of caffeinated soft drinks that has a mean caffeine content of 35.2 milligrams. Assume the population standard deviation is 12.5 milligrams. At α=0.05, do you support or reject the organization’s claim using the test statistic?

The mean caffeine content μ of a certain energy drink is under examination. A measure taken on a random sample of size n = 16 yieldsx̄ = 2.4 g/l. (a) Assuming that the standard deviation is known to be σ = 0.3, find the 95 confidence interval for μ. (b) If that the standard deviation is unknown but the sample standard deviation is s = 0.3, find the 95 confidence interval for μ.

A bottle of soft drink states that it contains 500 ml. A consumer group is angry and claims that the bottles are actually under-filled. The group takes a random sample of 40 bottles and finds a mean of 492 ml, with a sample standard deviation of 10 ml. Is their claim valid using the 0.01 level of significance? Use the five-step procedure to answer the question and include the p-value.
