Finish Up the Table

The Consumer Reports Restaurant Customer Satisfaction Survey is based upon 148,599 visits to full-service restaurant chains (Consumer Reports website). One of the variables in the study is meal price, the average amount paid per person for dinner and drinks, minus the tip. Suppose a reporter for the Sun Coast Times thought that it would be of interest to her readers to conduct a similar study for restaurants located on the Grand Strand section in Myrtle Beach, South Carolina. The reporter selected a sample of 8 seafood restaurants, 8 Italian restaurants, and 8 steakhouses. The following data show the meal prices ($) obtained for the 24 restaurants sampled. Use a = 0.05 to test whether there is a significant difference among the mean meal price for the three types of restaurants. Italian Seafood Steakhouse $ 10 $ 14 $ 22 $ 15 $ 16 $ 19 $ 17 $ 15 $ 24 $ 16 $ 26 $ 24 $ 18 $ 22 $ 21 $ 20 $ 13 $ 24 $ 17 $ 21 $ 29 $ 25 $ 18 $ 31 Source Sum of Squares Degrees Mean Square F p -value of Variation (to whole number) of Freedom (to 2 decimals) (to 2 decimals) (to 4 decimals) Treatments 2 Error 21 Total The p-value is less than 0.01 What is your conclusion?
