Computation of nominal scale based on Amin's (2008) method was used for the demographic analysis. This nominal scale was used to obtain a range of values for the age of the respondents and many more. The choice of answers was based on a five-point Likert scale adapted from Bhatti and Qureshi (2007) ranking as 1 (strongly disagree), 2 (disagree), 3
