PPT-Inferential Statistics Confidence Intervals and Hypothesis Testing

Samples vs Populations Population All of the objects that belong to a class eg all Darl projectile points all Americans all pollen grains A theoretical distribution Sample Some of the objects in a class. Remember we saw The sample proportion will differ from the population proportion by more than the margin of error less than 5 of the time The Margin of Error for a sample of size n is 1 n Suppose we wanted to estimate a Population Mean rather than a Level of data .
