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:

The company has a hypothesis (that the soft - drinks contain less than 16 oz) and tests it using sample data. Interval estimation gives a range of values, and point estimation gives a single value as an estimate. Here, a claim is being tested, which is characteristic of hypothesis testing.

Answer:

B. Hypothesis testing
