4.13. Four samples have been collected randomly from a soil pit containing arsenic. These initial TCLP concentrations are 6.1, 4.2, 5.8, and 6.5 mg/L. Determine the number of samples required to estimate the true population mean at the 95% con- fidence level based on the difference between the initial mean and the TCLP value.
