The Consumer Reports Restaurant Customer Satisfaction Survey is based upon 148,599 visits to full-service restaurant chains. + 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 a local newspaper thought that it would be of interest to her readers to conduct a similar study for restaurants located in her city. 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. Italian $11 13 15 18 17 20 16 26 Seafood $15 18 O Ho: MItalian Ha: Italian 16 26 23 16 19 19 Steakhouse $23 19 24 25 22 = 21 27 Use a = 0.05 to test whether there is a significant difference among the mean meal price for the three types of restaurants. State the null and alternative hypotheses. Ho: MItalian # Seafood # Steakhouse Ha: Italian Seafood = Steakhouse 31 O Ho: MItalian = Seafood #Steakhouse H₂: Not all the population means are equal. O Ho: At least two of the population means are equal. H₂: At least two of the population means are different. Seafood Steakhouse Seafood # Steakhouse O Ho: Not all the population means are equal.
