Final answer:
When the p-value increases above 1.0, the evidence against the null hypothesis becomes weaker. It suggests no significant evidence to support the alternative hypothesis, and we fail to reject the null hypothesis.
Step-by-step explanation:
When the p-value increases above 1.0, it means that the evidence against the null hypothesis becomes weaker. The p-value represents the probability of obtaining results as extreme as the ones observed, assuming the null hypothesis is true. A p-value larger than 1.0 suggests that there is no significant evidence to support the alternative hypothesis, and we fail to reject the null hypothesis.
If the p-value is less than or equal to 0.05 (or any predetermined significance level), it is generally considered statistically significant, and we reject the null hypothesis in favor of the alternative hypothesis. However, if the p-value is higher than 0.05, we do not have enough evidence to reject the null hypothesis and cannot conclude that there is a significant effect or relationship.
