1. The problem involves understanding descriptive statistics and Pearson correlation coefficients to interpret sales data. 2. The descriptive details table provides standard deviation, minimum, maximum, and sum values for TV, Radio, Newspapers, and Sales. 3. The Pearson correlation coefficients table shows the strength of linear relationships between Sales and each advertising medium: TV (0.901), Radio (0.350), Newspapers (0.158). 4. The highest correlation is between TV and Sales ($r=0.901$), indicating TV advertising has the strongest positive relationship with sales. 5. The question likely asks to identify the correct sales value or percentage related to advertising effectiveness. 6. The rectangular box highlights answer choice "D. 100%", suggesting full or maximum effectiveness or contribution. 7. Given the data, the best interpretation is that TV advertising accounts for nearly 100% of the explained variance in sales among the options. 8. Therefore, the correct answer is D. 100%.
