Question

Georgie believes that a special juice will increase the productivity of his workers. He creates two groups, two workers per group. Both groups are assigned the same task, stapling a set of papers. Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Georgie counts how many stacks of papers each group has stapled. Group A stapled 1,320 stacks while Group B stapled 2,200 stacks. Georgie concluded that the juice was not effective in improving productivity.

Answer 2

The answer is A. He should use more than two people per group.

Step-by-step explanation:

He only used two people per group, which can't fully prove his conclusion. He should test the experiment again with much bigger groups like about 50 or more. To add on to that, he only did one trial so he can't already call the experiment off. This gives further evidence of the significance of trials.
