State the multiple regression equation

Question 4, 14.6.42-T HW Score: 46%, 11.5 of 25 points : Homework: ASSIgnment 11 Pammw > O Points:00f6 In mining engineering, holes are often drilled through rock, using drill bits. It is expected that drilling time increases with depth. The business problem relates to whether drilling is faster using dry drilling holes or wet drilling holes. Data have been collected from a sample of drill holes that contains measurements of the time to drill each additional 5 feet (in minutes), the depth (in feet), and whether the hole was dry or wet. Use the accompanying data to complete parts (a) through (n). For parts (a) through (k), do not include an interaction term. Click he icon to view the data table. a. State the multiple regression equation that predicts the time, based on the depth, X1, and the type, X2. Dene X2 to be 0 for dry drilling holes and let X2 be 1 for wet drilling holes. Y. = + X1i + ( XZi (Round to three decimal places as needed.)
