Question: The effluent stream from a wastewater process is monitored to make sure that two process variables, the biological oxidation demand (BOD) and the solid content,

The effluent stream from a wastewater process is monitored to make sure that two process variables, the biological oxidation demand (BOD) and the solid content, meet specifications.

Sample no	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20
BOD (mg/l)	17.7	23.6	13.2	25.2	13.1	27.8	29.8	14.3	26.0	23.2	22.8	20.4	17.5	18.4	16.8	13.8	19.4	24.7	16.8	27.6
Solids (mg/l)	1380	1458	1322	1448	1334	1485	1503	1341	1448	1426	1417	1384	1380	1396	1345	1349	1398	1426	1361	1476
