Question

Which statement is true considering a significance level of 5%? The result is statistically significant, which implies that wearing a watch helps people manage their time better. The result is statistically significant, which implies that wearing a watch does not help people manage their time better. The result is not statistically significant, which implies that this result could be due to random chance. The result is not statistically significant, which implies that wearing a watch does not help people manage their time better.

Answer 1

The correct statement is: The result is statistically significant, which implies that the effect observed in the study is unlikely to be due to random chance and that wearing a watch may help people manage their time better.

Explanation:

In statistical analysis, a significance level of 5% (also known as the alpha level) is used to determine whether the results of a study are statistically significant. If the p-value (the probability of obtaining the observed results by chance if the null hypothesis is true) is less than the significance level, then the results are considered statistically significant. This means that the observed effect is unlikely to be due to random chance and may be a true effect.

However, it's important to note that statistical significance does not necessarily mean that the observed effect is practically significant or meaningful. It only indicates that the results are unlikely to be due to random chance. Additional factors, such as the size of the effect and the importance of the research question, should also be considered when interpreting the results of a study.
