between 'independent and dependent variables, the regression coefficient analysis
to measure the level of influence of independent variables on the dependent
variable. Level of significance test using the F test and t test. The author uses a
significant level of 5% to reject the null hypothesis. Statistical tests that will be
done partially and simultaneously.
