Hello!
You first have to look and see if there is an outlier
An outlier is something that is away from the rest of the data
All the numbers are with 1 from each other so there is no outliers
The answer is the first one
Hope this helps!
The group founded to prevent African Americans from exercising their civil rights was the Ku Klux Klan.
<u>Explanation:</u>
The Civil Rights Act of 1866 made African Americans(Radical Republicans) citizens of the US, prohibiting them from discriminating, which must be enforced in federal courts.

- Later Klans: 1950s–present
Each era has favored radical reactionary positions, such as white nationalism, anti-immigration and, in particular, the subsequent revivalism: Nordism and anti-Catholicism.
Answer:
(a): Marginal pmf of x


(b): Marginal pmf of y


(c): Mean and Variance of x


(d): Mean and Variance of y


(e): The covariance and the coefficient of correlation

Step-by-step explanation:
Given
<em>x = bottles</em>
<em>y = carton</em>
<em>See attachment for complete question</em>
<em />
Solving (a): Marginal pmf of x
This is calculated as:

So:






Solving (b): Marginal pmf of y
This is calculated as:

So:






Solving (c): Mean and Variance of x
Mean is calculated as:

So, we have:




Variance is calculated as:

Calculate 




So:




Solving (d): Mean and Variance of y
Mean is calculated as:

So, we have:




Variance is calculated as:

Calculate 




So:




Solving (e): The covariance and the coefficient of correlation
Covariance is calculated as:

Calculate E(xy)

This gives:




So:




The coefficient of correlation is then calculated as:
