M6 discussion - Assignment Example equired (examining whole population will take much more time than a sample), budget is limited (cost of examining few individuals will be low as compared to whole population), or sensitive information (such as sexual harassment in a large organization) is examined. A population proportion may be appropriate to use when population is small, required sample size is close to population, database already exists (if the data are on disk, we can examine 100% of the cases), or there is a legal requirement (The 2010 decennial population census). The large sample confidence interval is a range (or an interval) of values used to estimate the population characteristic. The interval is estimated using sample data. A confidence interval is associated with a confidence level (such as 95% or 99%) that gives us the success rate of the procedure used to construct the confidence interval. The confidence level is the probability that the confidence interval actually does contain the population characteristic, assuming that the estimation process is repeated large number of times. A large sample confidence interval can be constructed for a single proportion or for a difference in proportions. The large sample confidence interval can be used for making inference from the biological experiments. For example, suppose we take a sample of seeds for any given plant and count the number of germinated seeds. Now, from this sample proportion, we can give an estimate of population proportion for the number of seeds that will be germinated by using the large sample confidence interval for a single proportion
