To find the mean you have to add the numbers then divide them by the number of numbers are shown so you would do 20+14+29+39+33+25+19+35=214 214/8=26.75
To find the range you have to but the numbers in order so it would be 14, 19, 20, 25, 33, 35 39 and then start crossing them off until you are down to 1 or 2 numbers, in this case you have 1 left so it would be 25
The answer is A
