Question

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

Answer 1

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
