Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
It's very easy!

First of all, add up all the amounts of all can flavors.
.
What do you think it approximates to?
.
I'd say 245.
.
Now, how much is 30 out of 245?
.
Around 24%.
.
So, what's 245/100? (100 because it is default maximum percentage number)
<span>.
</span>2.45.
.
24 divided by 2.45?
.
Around 9%.

Your best guess is 10% or D.
5/6
