Question

Determine

mu Subscript x overbarμx

and

sigma Subscript x overbarσx

from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate.

u= 40​

σ= 8

n=23

A. mu Subscript x overbarμx=40​,

sigma Subscript x overbarσx=1.668

B. mu Subscript x overbarμx=.094​,

sigma Subscript x overbarσx=.668

C.mu Subscript x overbarμx=40

sigma Subscript x overbarσx=0.348

D. mu Subscript x overbarμx=40

sigma Subscript x overbarσx=8

Answer 1

Solution :

Given that,

mean = = 40

standard deviation = =8

n = 23

=    = 40

₌ / n = 8 23 = 1.668

A. mu Subscript x overbar μx=40​,

sigma Subscript x overbar σx=1.668
