Students investigating the packaging of potato chips purchased 6 bags of Lay's Ruffles marked with a net weight of 28.3 grams. They carefully weighed the contents of each bag, recording the following weights fin grams): 29.3, 28.2. 29.1. 28.7, 28.9, 28.5 (this gives us a mean of 28.78 grams and a standard deviation of 0.40 gams). Test appropriate hypotheses to see if the actual average weight is greater than the advertised weight on the packaging. Use a significance level of 5 percentage.

(i) Write out the Null and Alternative Hypotheses in symbols and words.

(ii) Using a test statistic, test the hypothesis at the 5% level of significance.

(iii) State your conclusion using the context of the problem.
