The probability that the mean clock life would differ from the population mean by greater than 12.5 years is 98.30%.
Given mean of 14 years, variance of 25 and sample size is 50.
We have to calculate the probability that the mean clock life would differ from the population mean by greater than 1.5 years.
μ=14,
σ=
=5
n=50
s orσ =5/
=0.7071.
This is 1 subtracted by the p value of z when X=12.5.
So,
z=X-μ/σ
=12.5-14/0.7071
=-2.12
P value=0.0170
1-0.0170=0.9830
=98.30%
Hence the probability that the mean clock life would differ from the population mean by greater than 1.5 years is 98.30%.

There is a mistake in question and correct question is as under:
What is the probability that the mean clock life would differ from the population mean by greater than 12.5 years?
Step-by-step explanation:
if 9 boxes is 42.75 then 1 box is 4.75 dollars
so 13 boxes would be 13X3.75 which is 61.75$
if 9b=$42.75
1b=x
9bx=$42.75b
x=$42.75b÷9b
x=$4.75
Answer:
Step-by-step explanation:
Option C 3 is the correct answer
The intersection between the complement of set A and the complement of set B is 7.
<h3>What is a Venn diagram?</h3>
A Venn diagram is a visual representation that shows mathematical sets as circular curves inside of a rectangle (known as the universal set).
From the Venn diagram, we are to find the intersection between the complement of set A and the complement of set B.
Therefore, the intersection between the two sets is the set of elements that exists in both of them. Therefore, we have:

Given y = 3x + 6, we find the x-intercept by setting y = 0 and solving the resulting equation for x: 0 = 3x + 6, or 3x = -6, or x = -2. The x - intercept is (-2,0).
Find the y-intercept by setting x = 0: y = 3(0) + 6 = 6. The y-int. is (0,6).
