Biologist in modern days usually use the term “oxygen demand†toexplain the amount of oxygen that is needed by aquatic organism tosurvive life. A group of biological scientist conducted a study ina particular swam area in order to know the average mean of oxygenneeded by this aquatic organism in that area for survival. Thescientist decided to take a random sample of 45 aquatic organismsin this area and measure the oxygen needed for their survival inmg/L. Conduct a confidence interval for true mean of oxygen neededfor survival in this area. The data are shown below in mg/L. 8.47.9 9.2 9.1 8.6 9.0 9.5 9.4 8.9 8.9 9.4 8.5 8.7 8.8 9 9.3 9.5 9.58.6 8.9 8.4 7.9 9.2 9.5 9.6 9.2 9.1 8.6 8.7 8.5 9.2 8.7 8.8 8.6 9.28.8 7.9 8.9 9.1 9.5 8.8 8.9 9.2 9.1 9.4
