Concerned about the initial monitoring data, the environmental action group decides to continue to monitor the plant, and try to gather more evidence for their case. A random sample of twenty-eight hours is selected over a period of a week. The observations (gallons of wastewater discharged per hour) are 887 1129 1095 1167 1162 1051 1146 904 1006 1302 1131 1145 1051 1091 982 1187 1068 1217 1107 1175 1187 1143 1206 975 942 1164 1027 1172 The output of a statistical analysis software on this dataset is shown below Mean 1100.7 N 28 Reading the output, we find that • The sample size is n = • The sample mean is π = • The sample standard deviation is s = S • From this we can calculate the standard error to be SE = √n || Std. Dev. 100.1
