Question

evaluate $\mu - 2\sigma$ when $\mu = 10.47$ and $\sigma = 4.84$.
the value of $\mu - 2\sigma$ when $\mu = 10.47$ and $\sigma = 4.84$ is
(type an integer or a decimal. do not round.)

Explanation:

Step1: Substitute the values into the formula

We have the formula \(\mu - 2\sigma\). Substitute \(\mu = 10.47\) and \(\sigma=4.84\) into it. So the expression becomes \(10.47-2\times4.84\).

Step2: Calculate the product

First, calculate \(2\times4.84\). Using the multiplication operation, \(2\times4.84 = 9.68\).

Step3: Calculate the subtraction

Now, calculate \(10.47 - 9.68\). Using the subtraction operation, \(10.47-9.68=0.79\).

Answer:

\(0.79\)
