Score reflects difiers' overall satisfaction. with higher values indicating greater overall satisfaction. A score of B9 can be interpreted as very satisfied. (tet x, represent average meal price, x2 represent type of restaurant, and y represent overall customer satisfaction.) (a) Develop the estimated regression equation to show how overall customer satisfaction is related to the independent variabie average meal pnice (Round your numenci values to two decimal places.) ^= (b) At the 0.05 level of significance, test whether the estimated regression equation developed in part (a) indicates a significant relationship between overall rustomer satisfaction and average meal price. (Use an F test.) State the null and alternative hypotheses. H0:10Ha:10H0:10Ha:1>0H0:1=0H0:10 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value.

There is insufficient evidence to conclude that there is a significant relationship. Do not reject H0. There is sufficient evidence to conclude that there is a significant relationship. Do not reject H0. There is insufficient evidence to conclude that there is a significant relationship. (c) Develop a dummy variable that will account for the type of restaurant (Italian or seafood/steakhouse). Let x2=1 if the restaurant is an Italian restaurant and xy=1 if the restaurant is a seafood/steakhause. Let x2=0 if the restaurant is an Itallan restaurant and x2=0 if the restaurant is a seafood/steakhouse.

Predict the Consumer Reports customer satisfaction score for a seafood/steakhouse that has an average meal price of $25. (Round your answer te two decimal places.) How much would the predicted score have changed for an Italian restaurant? (Round your answer to two decimal places.) The predicted satisfaction score increases by points for ftalian restaurants.
