Question
The pH for maximum activity of B-amylase enzyme is measured six times. The results are 5.15, 5.25, 5.45, 5.20, 5.50, and 5.35. a) What is the best estimate of the optimal pH (you need to calculate the mean)? b) How reliable is this value (you need to calculate the standard error of the mean, ơm)? c) If the experiment were stopped after only the first three measurements were taken, what would be the result (mean) and its precision (standard error of the mean)? d) If an additional six measurements were made with the same results as the previous ones, how would this affect the values you obtained for the mean and the standard error of the mean for this experiment? (Just assume that you have 6 additional measurements, which are identical to the first original 6 measurements). You need to calculate the mean and the standard error of the mean now with 12 measurements.
