Answer #1

Solution:-

Sampling scenario
1) z-test (Normally distributed and known population standard deviation)
2) t-test (Not normally distributed and sample size is large enough)
3) t-test (Normally distributed and unknown population standard deviation
4) z-test (Known population standard deviation and sample size is greater than 30.)
5) Unclear (Sample size is low and less information about population)

    Consider a population with a quantitative variable for which we would like to estimate ne population mean. We do so by taking random samples and calculating the sample nean. Use this scenario for questions 14 and 15. 14. If the population is normally distributed, what does that imply for the sample mean? a. The sample mean will be non-normal for small samples sizes, but become more normal as the sample size increases. b. The sample mean is guaranteed to be...
