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 41.5 milligrams. Assume the population standard deviation is 12.5 milligrams. At =0.05, what type of test is this and can you reject the organization's claim using the p-value?

Group of answer choices

The p-value is 0.98, it is greater than =0.05, we fail to reject the null, the null is claim, the claim is supported.

The p-value is 0.04, it is less than =0.05, we reject the null, the null is claim, the claim is not supported.

The p-value is 0.02, it is less than =0.05, we reject the null, the null is claim, the claim is not supported.

The p-value is 0.90, it is greater than =0.05, we fail to reject the null, the null is claim, the claim is supported.
