Question

After exercise, some people will have hypotension (low blood pressure) and it could last for hours. This can cause dizziness, light headaches and possibly faint upon standing. It is believed that Endurance training could reduce the post-exercise hypotension. To prove this, a research studies 24 people, with similar physical condition, and 12 of them are randomly selected to go through the Endurance training, while the other 12 did not. Their systolic pressure (mmHg) after 30 minutes as below. Group Sample size W/ Endurance Training W/O Endurance Training Diff = W/ - W/O

Answer 1

Ho:- hypotension Endurance training do not help to reduce hypotension Mills Endurance training reduces hypotenson i.e. hat, Mall, mean with training mean without training 12 - el -

Test Statistic:- t- so- y sti m, D2 S= (n-1 sn + (2-1) s ² mitn₂-2 = x (7.5) ? + 11 (8)? 12+12-2 S = 7.7540 t = 114-107 707540 12 12 t = 2.21 Critical t oo with 22 df and 1.717 a 2.211 > 1.717, so we reject conclude that training will to a = 0.05 ins : help to and reduce . hypotension 2) Type I error could be made which is defined as Reject to when to is true. Thus we might conclude that training is effective infact it might not be- (option B).
