Step-by-step explanation:
We don't know how many cans Hudson bought.
We are told, he bought:
10 green balls
5 yellow balls
Each can has 2 green balls, so there are:
10/2 = 5 cans
How can we distribute 5 yellow balls in 5 cans? Simple!
5/5 = 1
Put 1 yellow ball in each can.
So, each can will have:
2 green + 1 yellow (balls)
So, each can has 1 yellow ball
Answer:
μ = 0.169
ME = 0.051
Step-by-step explanation:
The confidence interval is:
CI = μ ± ME
So the mean is the middle of the confidence interval, and the margin of error is half the difference.
μ = (0.118 + 0.220) / 2 = 0.169
ME = (0.220 − 0.118) / 2 = 0.051
