Question

The total population (N) is 920; the standard value at 1% level of probability is 2.58 with 99% reliability with sampling error (Se) of 1% or 0.01 and the proportion of the target population is 50% or 0.50. Compute for the sample size. Show your solution.
Briefly explain the importance of laboratory animals in conducting research.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
