Calculate The Population Variance And Population Standard Deviation For The Following Data Said If Necessary Round To One More Decimal Place Than The Largest De class=

Sagot :

Given the dataset

2, 3, 4, 5, 6, 7, 8, 9, 10, 11

range is given by

[tex]range=maxValue-MinValue[/tex][tex]range=11-2[/tex][tex]range=9[/tex]

Range=9

population variance is given by

[tex]s^2=\frac{SumSquares}{n}[/tex][tex]s^2=\frac{82.5}{10}[/tex][tex]s^2=8.25[/tex]

rounded

population variance = 8.3

population standar deviation is given by

[tex]std=\sqrt{\frac{SumSquares}{n}}[/tex][tex]std=\sqrt{8.25}[/tex][tex]std=2.872[/tex]

rounded

population standar deviation= 2.9
