In this section you learned some of the foundational material for the rest of the course for inferences.   All data are either qualitative or quantitative.    If you have qualitative data, there will be some claimed value of __p_ for the population and you will compute some value of _p ?___ from the collected […]

In this section you learned about an amazing result about the sampling distribution of the sample proportion.   All data is either qualitative or quantitative.  In the last section we learned how to make probability computations and use them to make inferential decisions using ___ ________________ data and the random variable ___.  In this section […]

In this section you learned about the most amazing result about the sampling distribution of the sample mean.   Define sampling distribution:   Define sampling error:    Turn to page 211 and fill in the following formulas:    μ_x ? =μ_x  and σ_x ? =   To check if the sampling distribution of the sample […]

In this section you learned how to check to see if it is reasonable to assume that the sample data came from a normal population.   •             To be able to assume that it is reasonable to assume sample data came from a normal population, you need the following conditions […]
