Since 1930, the FIFA Mens world cup winners have scored anywhere from 70 up to 171 goals through the tournament. Suppose that we randomly select three of the previous winners and the total goals for those winners are 158, 98, and 124. Find the Standard quizlet

Respuesta :

The standard deviation is of: 30.09 goals.

------------------

  • The mean of a data-set is given by the sum of the observations divided by the number of observations.
  • The standard deviation is the square root of the sum of the differences squared between each observation and the mean, divided by one less than the number of values.
  • The data-set is: 158, 98, 124

------------------

The mean is of:

[tex]M = \frac{158 + 98 + 124}{3} = 126.67[/tex]

Thus, the standard deviation will be of:

[tex]s = \sqrt{\frac{(158-126.67)^2 + (98-126.67)^2 + (124 - 126.67)^2}{2}} = 30.09[/tex]

The standard deviation is of 30.09 goals.
