a simple random sample of 100 observations was taken from a large population. the sample mean and the standard deviation were determined to be 1,234 and 160 respectively. what is the standard error of the mean?

Respuesta :

The standard error of the mean for the large population is found as 16.

What is termed as the standard error?

  • The standard error (SE) is a statistical sample population's approximate standard deviation.
  • The standard error refers to the disparity between the population's calculated mean and one that is considered known or acknowledged as accurate.
  • The lower the standard error, the more number of data involved in the mean calculation.

For the given question;

The data for the large population is given as;

  • Mean μ = 1,234.
  • standard deviation σ = 160
  • Sample size n = 100

The standard error is estimated as;

SE = σ/√n

Put the values.

SE = 160/√100

SE = 160/10

SE = 16

Thus, the standard error of the mean is found as 16.
