a) mean=
b) median=
c) mode=
d) range=
is a) 53.17 b) 54 c) 37 and 46 d) 40
if they are wrong can you tell me why?

They are all correct.
A is correct because the mean is the sum of all the numbers (638) divided by the quantity of numbers (12)
B is correct because if you arrange the numbers in order from lowest value to greatest value, the 2 middle numbers are 53 and 55, and 54 is the # between those two
C is correct because mode is the numbers that occur the most often. 37 and 46 both occur twice
D is correct because the range is the greatest number (76) minus the smallest number (36)
