- Calculate the regression coefficients from the following :

x: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

y: | 3 | 7 | 10 | 12 | 14 | 17 | 20 | 24 |

2.State t-test and its applications for small samples.

3.If the regression coefficient are 0.8 and 0.2 , what would be the value of coefficient of correlation?

Answer: Go through the below link for answer :## 3.If the regression coefficient are 0.8 and 0.2 , what would be the value of coefficient of correlation?

Answer:Let rx=0.8, ry=0.2

Coeff. of correlation=Geometric Mean of Regression Coeff.

=√(0.8 x 0.2)

=√(0.16)

= 0.4

Coeff. of correlation = 0.4
