You are the VP, Advertising for "Yo' Mama" brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week's annual budget meetings and you have decided to make one of the following recommendations regarding next year's advertising campaign, depending on your statistical analysis of sales data (given below) from a probability sample of typical stores: (1) maintain the current African-American-focused campaign if average monthly per store sales to African-American customers are higher than the average monthly per store sales to Hispanic customers; (2) move to an Hispanic-focused ad campaign if the average monthly per store sales to Hispanic customers are higher than the average monthly per store sales to African-American customers; or (3) introduce a "balanced" campaign that seeks an equal ethnic mixture if average monthly per store sales are statistically the same. Using an alpha of.05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you have.
