Linear regression (Ch.10)
The linear regression is a problem of relating the
mean value of a single r.v. Y to a single independent
variable x using a linear relationship.
Suppose we have a

Correlation
Let X and Y be two not necessarily
independent random variables. Their joint
probability distribution function is
F ( x, y ) = P ( X x, Y x ) .
If X and Y are discrete, then th

Tests for two samples (sec.9.1)
Suppose you would like to compare the mean price of a
home in one state with that in another.
If you have got two independent random samples of
size n 30 (la

Hypotheses testing
Let a statistical model be given:

Different hypotheses may be posed about this
model.

Continuous r.v.
Suppose a r.v. X takes values from [0,1] with
equal probabilities. Simple events points of
