You have asked people to rate a product on a 1 to 10 scale. You have divided your results into two samples: people from urban areas, and people from rural areas. You wish to show that there is a difference between the two groups in how they rate the product. You have no prior belief about which will be more than the other, however. The appropriate statistical test in Excel produces the results shown below. Answer these questions:

(a) State the null hypothesis and the alternative hypothesis. Be sure it is clear which you are saying is the null and which is the alternative.

(b) Which statistical test is appropriate? [Your choices are one mean, one proportion, two means for related samples, two means for independent samples, or two proportions]

(c) Can you conclude that there is a difference between the two groups? Explain why or why not.
