Sample size The process of determining the proper sample size was established through a series of calculations and after obtaining all the possible sample sizes‚ the largest one was taken into consideration to collect the closest number to a representative sample of the population. The following two equations where used: Equation 1: N=z2 *(p.q) E2 N= sample size Z=level of confidence interval at 95% so z=1.96 P=estimated percent of population E=acceptable sample error expressed
