If the value of μ is 65, σ is 5 and z is 1.14 then the value of possible voter age would be 70.6 years.
Given that value of μ is 65, σ is 5 and z is 1.14.
We have to calculate the possible voter age that can satisfy the given values of σ,μ and z.
We know that in z test,
z=X-μ/σ
in which μ is population mean,σ is population standard deviation.
We have to just put the values in the above formula to get the value of X which is our possible voter age.
Putting the values we get,
1.14=x-65/5
5.7=X-65
X=65+5.7
X=67.7
Hence the possible voter age is 67.7 which would satisfy the value of μ=65,σ=5 and z=1.14.

Answer:
It depends on the different ones. Others last longer than others.
Answer:
D. 1.30
Step-by-step explanation:
As you can see on the number line, since there are 10 markings between the marks of 1 and 2, we can divide that to get the value that each marking represents.
Hence, each marking represents a change of , which would equal to .
Therefore, A would be 1 + (3 ), which equals to 1.3.
(As for why it would be 1 <em>+ </em>(3 ), that is because we can deduce the number line grows as it goes to the right due to the main markings (0, 1, 2) also growing as they go towards the right.)
Hope this helped!
The answer is c.
When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.
In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.
