Vera_Pavlovna [14]

Answer:

The standard error of mean = 10

Step-by-step explanation:

Given a simple sample of 144 observations was taken from a large population.

The size of large sample 'n' = 144

Given sample mean and the standard deviation were determined to be 1234 and 120 respectively.

Given standard deviation of sample (S) = 120

The standard error of mean is determined by

$SE (X^{-} ) = \frac{S.D}{\sqrt{n} }$

$SE (X^{-} ) = \frac{120}{\sqrt{144} } = 10$

Final answer:-

The standard error of mean = 10
