Unformatted text preview: pH=8, than at a low pH level, pH=5. He performs an experiment to measure the enzyme activities in M/min at the tow pH levels. The results of the experiment appear in the table below. Based on these results and using a 0.05 signicance level, can the biochemist conclude that the mean activity of the enzyme is higher at pH=8 than at pH=5? pH= 5 pH=8 n 1 = 16 n 2 = 9 x 1 = 0.70 x 2 =1.30 s 1 = 0.12 s 2 =0.26...
