what are the means and standard deviations of A and B?

anonymous · Answer

Are you suppose to get 2 different means? a and then b? or are you suppose to add them together. The way to find the mean to something is add it up then divide by the number of things. for instence:
 A: 80+85+87+92+86+90+100+75+45+85+38+72+94+62=1091
then you had 15 numbers you added SOOOOOOO then devide 1091/15 and you get 72.7 as your answer for A.
