Answer:
8.8
Step-by-step explanation:
set up a system
let x be sour keys and y be chocolate bars
2.65=15x+2y
3.35=10x+3y
then solve
X turns out to be 0.05
y turns out to be 0.95
multiply : 24*0.05=1.2
multiply : 0.95*8=7.6
add : 1.2+7.6 = 8.8
Calculate the standard deviation for each data set:
Sample A = 1.246
Sample B = 2.924
The smaller the deviation the closer the data set is, the larger the deviation the more widespread the data set is.
Sample B has a larger deviation so the spread of the data is wider.
