Answer:
The option B is True
Step-by-step explanation:
Solution
nA < nB
Thus
1/√nA > 1/√nB
SD/√nA > SD/√nB
So,
SE (A) > SE (B).......(1)
Zα/2 SE (A) > Zα/2 SE (B)
Now
E (A) > E(B) this is the margin error
Since SE fro sample A is larger than SE for sample B
We have that,
The length = ZE
Therefore, option B is correct because here, we know that as the sample size increases or goes higher the length of the confidence interval decreases
In this case, the sample size is large for B then A.
Thus, the length of confidence interval based on A is larger than the length of confidence interval Based on B Since SE is large For A than B

<span>To calculate the average; add up all the numbers, then divide by how many numbers there are. In this case, there are 5 numbers; personal, small, medium, large, and extra large.
