I need help with 1.8 and 1.9, please. They are related, that's why I didn't post them separately.

Transactions Task 1 Task 2 Task 3-4 Task 5-6 Task 7 Task 8-9 Task 10 A B C D E F G H I J 1 Which of the statements is correct about your final 1.8 model (with all significant independent variables). Which of the statements is correct in regards to the 1.9 parameter estimates (beta coefficients). 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 Place your final model beginning in cell E3. parameter estimates (beta coefficients). for intercept is 3.12 for profit is 0.72 for cost is 0.107 for customers' rating is 9.479 (1.8) Your objective is to create a profit prediction model that considers Customers' Ratings and Customers' Age. Develop this model specifically for the top four brands, based on quantity sold, and determine which of the following statements accurately describes your final model (the regression analysis output with ONLY significant variables remaining). - Filter the transaction data after identifying the top four brands, based on quantity sold. - Copy and paste the columns needed to the Task 8-9 worksheet to the right of the yellow field beginning in cell Q3. - You can do as many models as you need. - Place your final model (regression analysis output with ONLY significant variables remaining) beginning in cell (E3. - There should be ONLY one model on the Task 8-9 worksheet. - Select your answer to the question from the drop down in cell B6. (1.9) In the final model (with only significant independent variables remaining) you created for 1.8, which of the following statements is correct in regards to the parameter estimates (beta coefficients). - Select your answer from the drop down in cell (B6).
