estimating the probability that each item in the population has of being included in the sample.

Information Please Almanac. Suppose that a preliminary simple random sample of residents of San Francisco is used to develop a planning value of 6.25 minutes for the population standard deviation. If we want to estimate the population mean travel-to-work time for San Francisco residents with a margin of error of 2 minutes‚ what sample size should be used? Assume 95% confidence. Sample size=((1.96)^2 (〖6.25)〗^2)/2^2 =37.52 Sample size should be used 38. If we want to estimate the population

Unlike the various sampling techniques that can be used under probability sampling (e.g.‚ simple random sampling‚ stratified random sampling‚ etc.)‚ the goal of purposive sampling is not to randomly select units from a population to create a samplewith the intention of making generalisations (i.e.‚ statistical inferences) from that sample to the population of interest
