Dr Eberhardt has been conducting a study in which he wants to know how much glucose is generated by blue-green algae when they are placed under blue light for 4 hours. There are two methods that he can used to determine glucose levels and he needs to know which one is more accurate. In method 1, a hexokinase activity assay is used and the mean of 10 algal samples is 120 mmol, with a standard deviation of 4.8 In method 2, a glucose oxidase activity assay is used and the mean of the same 10 algal samples is 100, the standard deviation is 4. Which method is more accurate
