Solution
Given:
- • Robert drank 5, 8, 3, 6, 2, 9 and 14 cans of Slurp Soda respectively on each of the the 7 days in a week
To find:
- • The product of Robert’s mean and median soda consumption for that week
Approach and Working:
- • Mean = \(\frac{(5 + 8 + 3 + 6 + 2 + 9 + 14)}{7} = \frac{47}{7} = 6\)
• Median = 6
• Therefore, mean * median = \(\frac{47}{7} * 6 = \frac{282}{7} = 40.3\)
Hence, the correct answer is Option E
Answer: E
