(10 marks) For a study of balance in elderly people, a researcher randomly selected 20 consenting individuals over the age of 70 from a local community centre. Each participant stood on a “force platform”. They were instructed to press a hand-held button as quickly as possible in response to hearing a randomly timed buzzer. The subsequent forward-backward sway of the individuals was measured (in mm). The researcher would like to know whether elderly people sway more than 18 mm (the...
