A researcher is interested in determining if younger individuals are better at maintaining their balance than older individuals. To test this, individuals were asked to stand on one foot and press a button when they heard the buzzer go off. The amount of sway in the individual’s position (in mm) was recorded. The summary of the findings is provided in the table below: Sample n s Elderly 9 22.2 10.3 Young 8 15.13 3.91 Use a 95% level of confidence to estimate the difference in mean sway between the groups and you may assume that the amount of sway in each group is approximately normal. Would it be reasonable to support the claims of the researcher? Explain fully.
