Answer:

Null hypothesis is when there there are no significant difference in the specified population, or that is observed because of error in sampling or in the experiment

The alternative hypothesis is the opposite of the null hypothesis stating a different conclusion rather than a null hypothesis

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.

Alternative hypothesis:Athletes do not perform better in a competition when they have a stress management meeting the week before the competition

What conclusions can be drawn from this study with a "statistically significant" result?

Statistical significance is a determination by an analyst that the results in the data are not explainable by chance alonehis test provides a p-value, which is the probability of observing results as extreme as those in the data, assuming the results are truly due to chance alone
