The position of the mean and standard deviation are shown in the diagram below:
The mean is value at the center of the distribution
The standard deviation is the difference between the mean and the first value to the right
Comparing the given graph to the diagram above, we can conclude that:
[tex]\begin{gathered} \mu\text{ = -9} \\ \sigma\text{ = -8 - \lparen-9\rparen} \\ =\text{ -8 + 9} \\ =\text{ 1} \end{gathered}[/tex]
Answer:
[tex]\begin{gathered} \mu\text{ = -9} \\ \sigma\text{ = 1} \end{gathered}[/tex]
