Table 4.6 above indicates the result of reliability test for this research which is within acceptable range as shown in Table 4.5, rule of thumb
of the strength. Thus, it can be concluded that all the variables are acceptable and reliable in this research.

4.6 Multicollinearity Analysis

Based on Daoud (2018), multicollinearity is referring to the statistical phenomenon in which two or more variables in a multiple regression
model are highly correlated. He also stated that multicollinearity occurs when two or more independent variables in a regression model are
correlated. Therefore, the multicollinearity test was conducted in this study which refers to the results of Tolerance and Variance Inflation
Factor (VIF) accordingly. Apart from that, the value of Tolerance must be greater than 0.2 (Garson, 2012). Meanwhile, the value of VIF
must be less than 10 (Pallant, 2015). Thus, Table 4.7 below shows the results of multicollinearity test of this research.

a. Dependent Variable: Consumers’ Intentions

According to Table 4.7 above, the results indicate multicollinearity of this research is highly correlated due to value of Tolerance of all
independent variables are greater than 0.2 which knowledge (0.6730), attitude (0.456), subjective norms (0.696), perceived behavioural
control (0.953) and awareness (0.565) on consumers’ intentions. Meanwhile, the value of VIF for each variable are smaller than 10 which
range between 1.050 to 2.194. Thus, based on the result shown in table above, there is no issue of collinearity among the variables in this
study.
