Question

Determine

mu Subscript x overbarμx

and

sigma Subscript x overbarσx

from the given parameters of the population and sample size.

muμequals=8686​,

sigmaσequals=1818​,

nequals=8181

mu Subscript x overbarμxequals=nothing

sigma Subscript x overbarσxequals=nothing

Answer 1

Solution :

Given that,

mean = = 8686

population standard deviation = =1818

sample size. n = 8181

= 8686

  =  ( /n)

= (1818 / 8181 )

= 20.1

  = 20.1
