Question

a local fast food company sells a 16 - oz soft drink. to determine if the soft drinks served contain less than the advertised 16 oz, a random sample of 20 drinks is chosen and the amount of drink in each cup is measured (without ice). the mean amount of soft drink was found to be 15.5 oz with a standard deviation of 0.4 oz. based on the sample results we cannot claim that the soft drink contains less than 16 oz. which form of statistical inference does this conclusion represent? a. interval estimation b. hypothesis testing c. point estimation

Explanation:

Interval estimation provides a range of values for a population parameter. Point - estimation gives a single - value estimate. Hypothesis testing involves making a claim (null hypothesis) and testing it against sample data to decide whether to reject or fail to reject the claim. Here, a claim about the amount of soft - drink (less than 16 oz) is tested using sample data and a conclusion is drawn about the claim, which is hypothesis testing.

Answer:

B. Hypothesis testing
