version 21.0 (IBM SPSSInc., Chicago, IL) and STATA 11 were used.

variables. Normality of data was tested using Kolmogorov-Smirnov test
and Shapiro-Wilk test. Both descriptive and inferential statistics
involving Pearson Chi-Square, Fisher’s exact test, Pearson Correlation,
One Way ANOVA (Analysis of variances) Test, were used to present
results. A p-value of less than 0.05 was considered statistically
significant.

carried 0 mark, also question consist of more than one correct answers
