Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
the mean of a population being sampled is 64, and and the standard deviation is 6.
if the sample size is 50, the standard error of the mean is
. (round off your answer to the nearest hundredth.)

The standard error of the mean is 0.85

Step-by-step explanation:

* Lets revise some definition to solve the problem

- The mean of the distribution of sample means is called the expected

  value of M  

- It is equal to the population mean μ

- The standard deviation of the distribution of sample means is called

  the standard error of M

- The rule of standard error is σM = σ/√n , where σ is the standard  

  deviation and n is the size of the sample

* lets solve the problem

- The mean of a population being sampled is 64

∴ μ  = 64

- The standard deviation is 6

∴ σ = 6

-  The sample size is 50

∴ n = 50

∵ The standard error is σM = σ/√n

∴ The standard error is σM = 6/√50 = 0.8485

* The standard error of the mean is 0.85
