Fritos® As a project for an Introductory Statistics course, students checked 6 bags of Fritos marked with a net weight of 35.4 grams. They carefully weighed the contents of each bag, recording the following weights (in grams): 35.5, 35.3, 35.1, 36.4, 35.4, 35.5. Is there evidence that the mean weight of bags of Fritos is less than advertised?

a) Write appropriate hypotheses.

 b) Do these data satisfy the assumptions for inference? Explain.

 c) Test your hypothesis using all 6 weights.

 d) Retest your hypothesis with the one unusually high weight removed.

 e) What would you conclude about the stated net weight?
