05 TtestLinreg Tests the significance of the slope for the linear regression and its
correlation coefficient ρ.
Example
The test is for the slope β, and correlation coefficient ρ obtained
from statistical data X {65, 56, 78, 86, 92, 71, 68} and Y {95, 59,
88, 78, 75, 68, 80} are not equal to zero (β & ρ ≠ 0.)
1. Input the above lists X and Y into lists L1 and L2, respectively.
2. Press S E 0
3. Enter the appropriate value
