A local fast food company sells a 16-oz soft drink. To determine if the soft drinks served contain < 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 < 16 oz. Which form of statistical inference does this conclusion represent?

Hypothesis testing.

Explanation:

In the given problem it has been claimed that the mean of the population amount is less than 16 oz. for this claim, a test is conducted using the sample of size 20 and it was concluded that there is no evidence to say that mean amount is less than the claimed amount. i. e 16 oz

Hence, it is an example of the hypothesis testing.
