Arandomly selected sample of 100 students had an average grade point average (gpa) of 3.2 with a standard deviation of 0.2.

the standard error of the sample mean is:
a. 0.020
b. 0.200
c. 1.600
d. 2.000

A. 0.020

Step-by-step explanation:

we calculate the standard error of the sample mean with the formula,

,

with E= standard error of the sample mean

s= standard deviation

n= sample

So,

s= 0.2

n= 100

i need the table so i can see

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
