You are an analyst for the Coral Cola Company and are interestedin the association between age and rating of a new type of soda(Irish-Cream Cream-Soda). You suspect that younger individuals willprefer the soda over older individuals which could be useful fordeveloping advertisement programs that can appeal to the populationthat likes Irish-Cream Cream-Soda the most (e.g., youngerindividuals). You conduct a study in which you allow participants(n = 15) to taste the new soda and rate how much they like it on ascale from 1 – 10 (1 being the “worst thing I ever tasted” to 10being the “best thing I ever tasted”). In addition, you recordtheir age. Use the 6 steps of hypothesis testing and SPSS todetermine whether there is an association between ratings ofIrish-Cream Cream-Soda and age. The data is provided below. Conductthe appropriate statistical test either by hand or via SPSS (listedat the bottom), record your answers on the answer sheet, and attachSPSS output.
