You missed this lecture however, you assume this covered all of topic 7
Topic 7: Inferential Statistics Estimating Sampling Error
Since we use standard deviation units and not simply the original values to interpret the normal
distribution, we transform the original values into standard deviation units or Zscores.
IF our data are normally distributed, we can estimate the probability of any range of values occurring
around the mean by converting the data into Zscores
If we drew every possible sample of a given size from a given population, the
