Final answer:
When running a regression analysis, we can estimate the intercept of the line without estimating the slope. Estimating only the intercept might lead to limited predictive accuracy.
Step-by-step explanation:
The question is asking about running a regression and only estimating the intercept. When running a regression analysis, we can estimate the intercept of the line without estimating the slope. The intercept represents the value of the dependent variable when the independent variable is zero. It is important to note that estimating only the intercept might lead to limited predictive accuracy, as it does not consider the relationship between the independent and dependent variables.
