a. What is the regression model? "Wedding Cost +xAttendance (Round to three decimal places as needed.) 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. OA. The slope indicates that for each increase of 1 in attendance, the predicted wedding cost is estimated to increase by a value equal to b₁. OB. The slope indicates that for each increase of 1 in wedding cost, the predicted attendance is estimated to increase by a value equal to b₁. OC. It is not appropriate to interpret the slope because it is outside the range of observed wedding costs. OD. It is not appropriate to interpret the slope because it is outside the range of observed attendances. Interpret the Y-intercept of the regression equation. Choose the correct answer below. OA. The Y-intercept indicates that a wedding with a cost of $0 has a mean predicted attendance of bo people. OB. The Y-intercept indicates that a wedding with an attendance of 0 people has a mean predicted cost of $bo- OC. It is not appropriate to interpret the Y-intercept because it is outside the range of observed attendances. OD. It is not appropriate to interpret the Y-intercept because it is outside the range of observed wedding costs.
