Inferences Concerning a Mean
7.1 Point Estimation
A Point Estimator is a statistic taken from the sample , used to estimate a
population parameter
A Point Estimate is the observed value of the estimator.
Paramter: Population mean
Data: A random sampl

Right-handed and left-hands systems
The system is right-handed or left-handed depending on
which hand points along the x-axis. In this text, you will
work exclusively with the
right-handed system.

The Method of Least Squares
For instance, the sum of the squared errors for the linear
model in Figure 13.74 is S 17.6.
Statisticians call the linear model that
minimizes S the least squares
regression line.
