The Probability Distribution of a Random Variable Is Given Along $\begin{array}{r|rrrrr}\mathrm{x} & 4 & 5 & 6 & 7 & 8 \\\hline \mathrm{P}(\mathrm{X}=\mathrm{x}) & 0.1 & 0.3 & 0.45 & 0.1 & 0.05\end{array}$

question 3

Multiple Choice

The probability distribution of a random variable is given along with its mean and standard deviation. Draw aprobability histogram for the random variable; locate the mean and show one, two, and three standard deviationintervals.
- $\begin{array}{r|rrrrr}\mathrm{x} & 4 & 5 & 6 & 7 & 8 \\\hline \mathrm{P}(\mathrm{X}=\mathrm{x}) & 0.1 & 0.3 & 0.45 & 0.1 & 0.05\end{array}$

$$\mu = 5.7 , \sigma = 0.95$$
