A chicken wings restaurant chain has developed two new special sauces, the 'cheesy-cheeses' and the 'super-duper hot' (let's better call them Sauce1 and Sauce2 respectively). The company has funds to invest in only one of the two sauces so management wants to determine which one is more appealing for customers. They randomly choose 80 of its restaurants around the country (all about the same size and overall sales volume) and offers Sauce1 at 40 of these sites, and Sauce2 at the other 40 sites. The file Sauces Data.xlsx has 80 observations on two variables: - Sales: number of chicken wings with each of the new sauces sold in the 40 restaurants during the first week of the promotion - Sauce Type: Sauce1 if the wings were sold with Sauce1; Sauce2 if the wings were sold with Sauce2. Management suspects that launching Sauce 1 is a better strategy and they want to test this hypothesis using the data from the 80 sample data. - The null Hypothesis Ho is [ Select ] - The alternative hypothesis Ha is [ Select ] - The t statistic is = [ Select ] - The p-value is = [ Select ] - The test indicates that: [ Select ]
