Use the probability distribution for the random variable x to answer the question. x 0 1 2 3 4 p(x) 0.12 0.2 0.2 0.36 0.12 Calculate the population mean, variance, and standard deviation. (Round your standard deviation to three decimal places.)

--- Mean

-- Variance

--- Standard deviation

Step-by-step explanation:

Given

Solving (a): The population mean

This is calculated as:

So, we have:

Solving (b): The population variance

First, calculate:

using:

So, we have:

So, the population variance is:

Solving (c): The population standard deviation

This is calculated as:

cosine

step-by-step explanation:

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
