Answer

Explanation:

Step1: Calculate mean of hamburgers

Mean = $\frac{9 + 25+25+13+23+30}{6}=\frac{125}{6}\approx20.83$

Step2: Arrange hamburgers data in ascending order

$9,13,23,25,25,30$. Median is $\frac{23 + 25}{2}=24$

Step3: Calculate mean of hot - dogs

Mean = $\frac{8+28+29+18+22+20}{6}=\frac{125}{6}\approx20.83$

Step4: Arrange hot - dogs data in ascending order

$8,18,20,22,28,29$. Median is $\frac{20 + 22}{2}=21$

Step5: Compare mean and median

Median of hamburgers ($24$) is greater than mean of hot - dogs ($20.83$)
