Question 8 The following information may be used in several questions An Italian rostaurant sources its cheose ravioli from a supplier that performs regular quality control checks to ansuro that its process is producing ravioli filed with the right amount of choose (on average). Today, inspectors took a sample of 25 ravioli and measured the average cheose fill, in grams. A 99% confidence intervel was found to be 14.16 to 15.84 grams Refer to te situation above involving techo se n violi supplior, and let Abe the mean fill, which the supplier wants to be 15grans. Agg% confdence interval was ound to be 14.16 grams to 15.84 grama. What can you say about a tost of the hypothos Ho - 15 H 15 at the a-0 01 evel of significance? Read carefully Oa Reject the nul hypothesis. Conclude that the mean cheose fill dffers from 15 Ob. Cannot determine without knowing the standard deviation, s Oc. Fail to rejoct the null hypothesis. Conclude that the mean choos it is more than 15 Od. Fail to reject the null hypothesis, Cannot conclude that the mean cheose fill difers from 15. Oa. Reject the null hypothesis. Conclude that the mean cheese fillis either 14.16 or 15.84.

Explanation / Answer

The calculated 99%CI is (14.16, 15.84)

The hypothesized mean as per null hypothesis is 15

If the hypothesized mean is included within the calculated CI, we fail to reject the null hypothesis.

Hence, Fail to reject the null hypothesis. Cannot conclude that the mean cheese fill differs from 15.

Option D is correct
