Answer:
The mean is 30000 and standard deviation is 9746.79.
Step-by-step explanation:
Formula of mean
[tex]Mean=\bar{x}=\frac{\sum x_i}{n}[/tex]
Formula of standard deviation:
[tex]S.D.=\sigma=\sqrt{\frac{\sum{(x-\bar{x})^2}}{n}}[/tex]
Using the below table.
[tex]Mean=\bar{x}=30000[/tex]
[tex]S.D.=\sigma=9746.794345\approx 9746.79[/tex]
Therefore the mean is 30000 and standard deviation is 9746.79.
