**Title: Analysis of Age Distribution Among Promotion-Sensitive Shoppers** **Overview:** This study evaluates the age distribution of customers identified as "super shoppers" at supermarkets. A "super shopper" is defined as an individual who purchases at least 70% of their items either on sale or with coupons. **Age Distribution Data:** | Age Group (Years) | Midpoint | Super Shoppers (%) | |-------------------|----------|--------------------| | 18-28 | 23 | 10% | | 29-39 | 34 | 43% | | 40-50 | 45 | 25% | | 51-61 | 56 | 11% | | 62 and over | 67 | 11% | **Objective:** Calculate the standard deviation (\(\sigma\)) for the ages of super shoppers, rounding the result to two decimal places. **Instructions:** To find the standard deviation, consider the midpoints of each age group along with their respective percentage of super shoppers. Use these to determine the variance and subsequently the standard deviation.
