Question

A beverage company claims that the average sugar content in its soft drinks is $30$ grams per bottle. A nutrition researcher collects a random sample and constructs a $95 percent sign$ confidence interval for the mean sugar content: ( $29.2$ grams, $29.8$ grams)
You are given the following null hypothesis: $H sub 0 colon mu equals 30$ grams
Does the confidence interval suggest that you should reject $H sub 0$ ? Explain your reasoning.

Accepted Answer

Yes, because 3030  is not in the confidence interval, so the null hypothesis should be rejected.

Answer

Yes, because 3030  is equal to the sample mean.

Answer

No, because 29.229.2  and 29.829.8  are close to 3030.

Answer

No, because 3030  is the midpoint of the interval.
