Question: Chapter 7 talks about sampling and sampling distributions. The calculations in Chapter 7 are an extension of the probability calculations that use the standard normal

Chapter 7 talks about sampling and sampling distributions. The calculations in Chapter 7 are an extension of the probability calculations that use the standard normal distribution in Chapter 6. The main difference between Chapter 6 and 7 is that in Chapter 7 we are substituting the standard deviation of x-bar (aka the standard error of the mean) as a substitute for the sample standard deviation.

In this week's discussion, describe what you see as the major concern with using a sample to draw conclusions about the population. What should a researcher, business owner or any other person conducting a scientific study consider when sampling a population in order to make sure that his results will give the best conclusions?
