Also, in order to examine the hypothesis of the study, inferential tests of Pearson correlation coefficient, one-way analysis of variance, multiple linear regression have been used baxsed on independent and dependent variables. The data derived from the questionnaires is analyzed baxsed on numerical method and has been implemented using SPSS software. Results: Pearson correlation coefficient test shows a positive and significant relationship between two variables with a coefficient of 0.79 and a significance level of 0.001. Levin F test is confirmed to evaluate the assumption of equality of variances with F = 0.56 and significance level of 0.45.
