A report indicated the many health benefits of consuming cheese as part of a healthy diet. It also claimed that the average sodium content in cheese is 1000mg per 100 g. Thinking this figure seemed high, a researcher decided to test this claim. A random sample of 14 different types of cheese was selected and the sodium content on the packaging recorded. This sample average sodium content was found to be 955mg per 100 g. If the population standard deviation of sodium content in cheese is 120mg per 100 g, using a 5% level of significance, test if the claim in the report has been overstated.
