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

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
