Determining Sample Size In the business world‚ sample sizes are determined prior to data collection to ensure that the confidence interval is narrow enough to be useful in making decisions. Determining the proper sample size is a complicated procedure‚ subject to the constraints of budget‚ time‚ and the amount of acceptable sampling error. If you want to estimate the mean dollar amount of the sales invoices‚ you must determine in advance how large a sampling error to allow in estimating the population

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

Size reduction and screening The purpose of this experiment was to determine the affect of vibration rate and time on the size reduction and size separation of particles. The objective was successfully completed and the initial sample of soil was separated by vibration into finer particles with a large amount passing through the smallest diameter screen which was 0.0278 inches producing a final product of fine soil particles which are now easier to transport and store. As can be seen from the
