For a population with a mean of u=72 and a standard deviation of o=10 what is the standard error of the distribution of sample means for each of the following sample sizes

For a sample of n=4
oM=

For a sample of n=25 scores
oM=

For a sample of n=4 , SE=5

For a sample of n=425, SE=2

Step-by-step explanation:

The standard error of the distribution is given by;

For a sample of n=4,

The standard error is:

For a sample of n=25, the standard error is

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
