... Figure 2 (a) shows the explained variation, which is expressed by the vertical distance between any_ fitted (predicted) value and the mean or yˆ i - y . The circumflex (^) over the y is used to represent fitted values determined by a model. Thus, it is also customary to write a = ̂ and b = ̂ . Fi ...

Chapter 20 Inference about a Population Mean
... This chapter is almost exactly like chapter 16 and 17 in that it is about confidence intervals and inference tests. The major difference is that the generally unrealistic condition that the population standard deviation is known is discarded. The details of finding a confidence interval and tests ar ...

t distribution
... Given the percent of each state's residents who are at least 65 years of age, can or should we use t to approximate the mean of these percents? Hint: This is a population not a sample. ...
