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 .
23/5, 5/2, 31/9, and 19/7
All you have to do is multiply the whole number by the denominator and add the numerator. For example:
5 3/6 5*6 is 30 +6 is 36
therefore the improper fraction is 36/6
