Random samples of size 36 with a mean and standard deviation of 20 and 15, respectively, are taken from a process (an infinite population). The distribution of the population is unknown.

The standard error of the distribution of sample mean is

(Round your answer to 1 decimal place.)

The formula for standard error of the distribution of sample mean is ?m= ?

?N Where ? So,

Thus, is the standard deviation and N is the sample size ? =15 and N = 36 ?m= 15 15 5

= = =2.5

?36…
