Part 2 b. Interpret all key regression​ results, hypothesis​ tests, and confidence intervals in the regression output from part a.   Interpret the slope of the regression equation. Choose the correct answer below.     A. It is not appropriate to interpret the slope because it is outside the range of observed attendances.   B. The slope indicates that for each increase of 1 in wedding​ cost, the predicted attendance is estimated to increase by a value equal to b 1b1.   C. It is not appropriate to interpret the slope because it is outside the range of observed wedding costs.   D.
