He summarized the data in the following frequency distribution table: Variable Frequency 5-9 2 10-14 15-19 8 20-24 10 25-29 4 1. In this scenario, identify the following: v Variable a. 5 -v Individual b. 29 v Class (bin) width C. a Starbucks - v Sample size d. the number of cappuccinos sold 2. Is the variable discrete or continuous? O discrete O continuous 3. What percent of Starbucks locations sold at least 10 cappuccinos?
