LinRegTTest
LinRegTTest (linear regression t test; item E ) computes a linear
regression on the given data and a t test on the value of slope b and the
correlation coefficient r for the equation y = a + b x. It tests the null
hypothesis H
0
: b =0 (equivalently, r =0) against one of the alternatives
below.

a
: bƒ 0 and rƒ 0 ( b & r : ƒ 0 )
•

a
: b <0 and r <0 ( b & r :<0 )
