Question

One thousand and twenty students participated in the school math contest.

Answer 1

Answer:

E)- Sample 2 has a higher median score than Sample 1.

Step-by-step explanation:

For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).

We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.

Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.

Answer 2

With the way its set up I would have to say the answer id E. due to the fact that the average, or median is higher in sample 2.
