The data below describe the effects of temperature on the traditional decay coefficient, $b.$ Use that data to determine the temperature coefficient by each of the three techniques. Use $20C$ as the reference temperature. Discuss the utility of each technique for describing the effects of temperature on this parameter $(5-$marks$)$

in which $b,c,T_{\text{m}\text{i}\text{n}},$ and $T_{\text{m}\text{a}\text{x}}$ are empirically derived coefficients. This expression has been applied successfully to suspended growth wastewater treatment systems. ${?}^{70,71}$
