Standard Normal T able
(https://previous.nursingabc.com/upload/images/Help_file_picture/standardnormaltable.pdf) Suppose that you take a sample of size 50 from a population that is not
normally distributed. Can the sampling distribution of x̄ be approximated by a
normal probability distribution?
Yes because the sample size could be approximated by a normal probability
due to the sample size being larger than 30.This study source was downloaded by 100000829725281 from CourseHero.com on 12-17-2021 14:02:49 GMT -06:00

Standard Normal T able
(https://previous.nursingabc.com/upload/images/Help_file_picture/standardnormaltable.pdf) Suppose that you are attempting to estimate the annual income of 1700
families. In order to use the infinite standard deviation formula, what sample
size, n, should you use?
the sample size is less than 85
In order to use infinite standard deviation formula, we should
have: n≤0.05(1700) n≤85
So, the sample size should be less than 85.This study source was downloaded by 100000829725281 from CourseHero.com on 12-17-2021 14:02:49 GMT -06:00
