Answer:
range=18
median=42
Step-by-step explanation:
for range find your highest value out of the list and your lowest value.
highest value-lowest value= range
in this case,
53-35=18
for median list your number from highest to lowest like:
35 37 41 42 48 49 51 53
cross off numbers from either side until you are left with the middle value
which is 42 in this case.
