Consider the probability distribution shown here. Complete parts a through c. \begin{tabular}{c|c c c c c c c c c} $x$ & -4 & -3 & -2 & -1 & 0 & 1 & 2 & 3 & 4 \\ $P(x)$ & 0.01 & 0.06 & 0.09 & 0.14 & 0.34 & 0.19 & 0.09 & 0.06 & 0.02 \\ \end{tabular} a. Calculate $\mu$, $\sigma^2$, and $\sigma$. $\mu = \boxed{}$ (Round to two decimal places as needed.)

Step 1
Given that the sum of all probabilities must equal 1, we can calculate the missing probability for x = 1 by subtracting the sum of the probabilities for x = -4, -3, -2, and -1 from 1. p(x=1) = 1 - (0.01 + 0.06 + 0.09 + 0.14) = 0.70 Show more…
