Inorganic phosphorous is a naturally occurring element in all plants and animals, with concentrations increasing progressively up the food chain (fruit < vegetables < cereaisenuts < corpse). Geochemical surveys take soil samples to determine phosphorous content (in ppm, parts per million). A high phosphorous content may or may not indicate anancient burial site, food storage site, or even a garbage dump. Independent random samples from two regions gave the following phosphorous measurements (in ppm).Assume the distribution of phosphorous is mound-shaped and symmetric for these two regions.Region It x n, 158571,551 1,2308751,080 2,330 1,850 1,8602,340 1,0809101,130 1,450 1,2601,010Region III xi n 14542 B061,230 1,7707909601,650 860890 640 1,180 1,160 1,050 1,020A USE SALT(a) Use a caiculator with mean and standard deviation keys to verify that a and s (Round your answers to four decimal places.)ppmppmppmppm(b) Let , be the population mean for x, and let be the population mean for .
