Krejcie and Morgan (1970) table was used todetermine a sample size of 191 from the target population, while, simple random sampling technique was employed to administer the questionnaire. The main research instrument used for this study was questionnaire and the data collected was analyzed using a Statistical Package for the Social Sciences (SPSS) version 17.0 and descriptive statistics of frequencies and percentages to present results in tables, pie charts and bar charts.
