Articulate a null hypothesis and alternative hypothesis for a research study that pertains to you're area of specialization.
Research focusing on sport psychology, hypothesizing that athletes will perform better when they have had a stress management meeting with a sport psychologist the week before their competition
Null hypothesis:Athletes perform getter in a competition when they have a stress management meeting the week before the competition.
