Question

A regression analysis was performed to determine which, if any, of protein (grams), total fat (grams), fiber (grams), carbohydrates (grams), and sugars (grams) are associated with calories in a sample of 34 breakfast cereals. Which of the following is the null hypothesis for the F-test in this problem? Choose the correct answer below. None of protein, total fat, fiber, carbohydrates, or sugars helps to explain calories in breakfast cereals. At least one of protein, total fat fiber, carbohydrates, or sugars helps to explain calories in breakfast cereals. Exactly one of protein, total fat fiber, carbohydrates, or sugars helps to explain calories in breakfast cereals. All of protein, total fat fiber, carbohydrates, or sugars help to explain calories in breakfast cereals. beta_i = 0

Explanation / Answer

Option (A)-An F-test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove.
