A consumer product testing organization uses a survey of readers to obtain customer satisfaction ratings for the nation's largest supermarkets. Each survey respondent is asked to rate a specified supermarketbased on a variety of factors such as: quality of products, selection, value, checkout efficiency, service, and store layout. An overall satisfaction score summarizes the rating for each respondent with 100 meaningthe respondent is completely satisfied in terms of all factors. Suppose sample data representative of independent samples of two supermarkets customers are shown below.Supermarket 1 Supermarket 27₁-280₂-3007₁-83(6) Formulate the null and alternative hypotheses to test whether there is a difference between the population mean customer satisfaction scores for the two retailers.
