Answer: d. 1.3333
Step-by-step explanation:
We know that the standard error of a sampling distribution is given by :-
, where
= Population standard deviation.
n= Sample size.
AS per given , we have
n=81
Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-

Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.
Thus the correct answer is d. 1.3333 .
Answer:
I don't have a price of paper near by but I can explain how do it
Step-by-step explanation:
start by puting them in numerical order and tally up how many are under each number. this is going to give you how common each number is on the table. ex: if there is a 2 in every box it would get a 20/20 because it would fill every box. with that you should be able to find where the most common are as well as the rest of the answers. I'm sorry I couldn't help more
Answer:
The answer is 7/3 or 2 1/3
Step-by-step explanation:
1) You change the ÷ into x (so it will be 7/9 x 1/3)
2) You flip the 1/3 so it will be 3 ( 7/9 x 3)
3) There you have it the answer is 7/3
First you solve for X then substitute the number you got for X and then solve for Y.
3*500 3* 80 3*4 that is your anser
