The independent variable explains only 23% of the variations in the response variable and hence should not be considered in the regression analysis.

The p-value indicates the independent variable is a highly significant source in explaining the variations in the dependent variable, and hence, the model is accurate.

Even though the independent variable explains only 23% of the variations in the response variable, it is a significant source, and the model must be expanded to include more explanatory variables.

More information is required to make an inference.
