Question: The data file RESTAURANTS contains the ratings for food, décor, service, and price per person for a sample of 50 restaurants located in an urban area and 50 restaurants located in a suburban area. At the .05 level of significance, is there evidence of a difference in the mean food rating between urban and suburban restaurants?

Complete the following:
  1. State H 0 .
\[{{\mu }_{1}}={{\mu }_{2}}\]
2. State H 1 . \[{{\mu }_{1}}\ne {{\mu }_{2}}\]
3. State the value of α. 0.05
4. State the value of the test statistic. 1.4843
5. State the p-value. 0.1409
6. State the decision in terms of H 0 and why. Fail to reject Ho (because p > 0.05)
7. State the decision in terms of the problem. There is not enough evidence to claim that there is a significant difference in the suburban and urban ratings

NOTE: The sample size is large enough to use normal approximation, but using t-test gives the exact statistic
