Assignment 4. 1. Given the following particular situations, identify which sampling design approach should be used and discuss why it is the most appropriate: a. If you are performing a screening phase of an investigation of a relatively small-scale problem, and you have budget and/or a limited schedule. Your goal is to assess whether further investigation including a detailed follow-up sampling is warranted b. If you are estimating a population mean and you have known the existence of spatial or temporal patterns of the contaminant. Your goal is to increase the precision of the estimate with the same number of samples, or achieve the same precision with fewer samples and lower cost. c. If you are estimating a population mean and you have an adequate budget. In the meantime, you are also interested in understanding the spatial or temporal pattern. d. If you are estimating a population mean and you have budget constraints. The analytical costs are much higher than the sampling costs. Your goal is
