Answer:
80
Step-by-step explanation:
Look at the box plot and look at each line.
The first line that is all the way to the left, that is the Quartile 1.
The last line all the way to the right, that is Quartile 3.
Now lets look at the box part.
The beggining of the box is the minimum.
The ending of the box is the maximum.
The middle line is the median.
How I remember it is Median=Middle
Hopw this hels :D
If you turn the ratio 1:3 into a fraction it would be 1 over 3 I hope this helps
So lets do it like this:
z = (X-Mean)/SD
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
I'm assuming we have to solve for "p" here...
By making an equation, we will get...
(p/4)-4=10
Add four on both sides...
(p/4)=14
Remove parentheses and multiply by four on both sides.
p=56
