Suppose that in a random sample of size 200, standard deviation of the sampling distribution of the sample mean 0.08. researcher
wanted to reduce the standard deviation to 0.04. what sample size would be required?
1 answer:
Answer:
400
Step-by-step explanation:
The computation of the sample size needed is shown below:
Since at the sample size of 200 there is a standard deviation of 0.08
But when the standard deviation is 0.04 so the sample size is 400
As sample standard deviation would be inversely proportional to the square root of the sample size

3/8 because 2+3+3=8. One pair of pants, one pair of shirt and one pair of shoes =3
You put this under mathematics when this has nothing to do with math. but just to help, i think groundhog day is usually in febuary. ;)
I’m pretty sure it’s C and if I’m wrong I’m very sorry I probably did some math wrong
