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:
315
Step-by-step explanation:

250 miles is equivalent to 400 kilometers.
We have,
To find out how many kilometers are equivalent to 250 miles, we can set up a proportion using the given information that 5 miles are equal to 8 kilometers.
5 miles : 8 kilometers
We can set up the proportion:
5 miles / 8 kilometers = 250 miles / x kilometers
To solve for x (the number of kilometers in 250 miles), we can cross-multiply and then divide:
5 miles x (x kilometers) = 8 kilometers x 250 miles
5x = 2000
Dividing both sides by 5:
x = 400
Therefore,
250 miles is equivalent to 400 kilometers.
