You have been hired by a fast casual restaurant to help them understand how customer service relates to profits. In addition, they are interested in any recommendations from your analysis. For the following questions please download the dataset "CustomerSurvey". The data contains four fields:

Profit: A measure of each restaurant's profit in thousands of dollars. In order to maintain confidentiality, the company has centered profits per restaurant so "0" means the restaurant has average profits, a negative number means the restaurant has less than average profit, and a positive number means that the restaurant has higher than average profits. Therefore, a restaurant with -50 profit means the store earned $50k less than average while a restaurant with +50 profit means the store earned $50k more than average profits.

Promoter: A measure of customer intentions. At the beginning of each year, a random sample of 1000 customers from each restaurant is surveyed in order to determine how likely each customer is to visit the restaurant again and how likely they are to tell a friend or family member about the restaurant. Each customer's responses are averaged to get an overall score for the specific restaurant. The score is such that higher is better (5= very likely and 1=very unlikely).

Satisfaction: A measure of customer attitudes. At the beginning of each year, a random sample of 1000 customers from each restaurant is surveyed in order to determine how satisfied each customer is with their experiences at the restaurant. Each customer's responses are averaged to get an overall score for the specific restaurant. The score is such that higher is better (5= very satisfied and 1=very unsatisfied).

Quality: A measure of customer experiences. At the beginning of each year, a random sample of 1000 customers from each restaurant is surveyed in order to determine how customer would rate the quality of service they received at the restaurant. Each customers responses are averaged to get an overall score for the specific restaurant. The score is such that higher is better (5=very good and 1 = very bad)

The survey responses were collected at the beginning of 2021 and the profits are for the full year 2021.
