It was determined that the sample mean weight of 10 randomly selected house cats was 8.4 pounds. We seek to create a 90% confidence interval for the population mean weight of house cats in the United States. The criteria n LaTeX: \le≤≤ .05N for constructing a confidence interval for the population mean weight of housecats is satisfied in this example. Group of answer choices True False
Solution:
It is
False
Explanation:
n is the sample size
N is the population size
When , n
0.05 N , then we can find the confidence interval for the mean
using regular formula.
If n
0.05 N , then we need to use Population correction factor.
In given example , n = 10
But N is not mentioned .
So we cannot say whether the criteria n
0.05 N for constructing a confidence interval for the population
mean weight of house cats is satisfied or not.
So ,
False
