Answer: proportion of candies are green.
Solution:
In bag A, candies are yellow.
this proportion shows ratio of favorable over total candies.
Here numerator number is 2.
So, Total number of yellow candies should be 2x
Total number of candies in Bag A would be 3x
Number of green candies in bag A = 3x-2x = x
Now we find the portion of green candies in bag A
portion of candies are green in bag A
A) Variance = 10.24
B) Standard Deviation = 3.2
One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

∑fd² = 552
Standard Deviation =
√4.35 - √1.15
Standard Deviation = 3.2
(SD)² = (3.2)² = 10.24
Variance = 10.24
