**. Correlation is significant at the 0.01 level (2-tailed).

A).

Correlation r= 0.629

b).

\ H_0: \rho = 0 \ \ \ H_1: \rho \neq 0


Calculated r= 0.629, P=0.003 which is < 0.05 level of significance. The null hypothesis is rejected.

There is significant linear correlation between income and level of education.

c).

The correlation is positive. Low income is associated with low levels of education.

Correlation does not imply causation. Cause and effect is not appropriate here. We are not supporting the conclusion that low levels of education cause low income.
