Question
**Problem Statement:** (b) Develop a quadratic trend equation. (Round your numerical values to four decimal places.) **Equation:** \[ T_t = 45.5019 + 8.9768t + 0.7009 \] An "X" mark is present next to the equation, possibly indicating an error or incorrect solution. **Explanation for Educational Context:** In this task, you are asked to develop a quadratic trend equation using given numerical values rounded to four decimal places. The quadratic trend equation is useful for modeling data that exhibit a curved trend over time. The equation above is incorrectly labeled as a quadratic trend since it lacks a squared term (typically \( t^2 \)) for the variable \( t \).

A statistical program is recommended. Suppose the following data shows a company's annual revenue from 2008 (period 1) to 2017 (period 10) in billions of dollars. | Year | Period | Annual Revenue (\$ billions) | |------|--------|-------------------------------| | 2008 | 1 | \$20.80 | | 2009 | 2 | \$24.65 | | 2010 | 3 | \$28.32 | | 2011 | 4 | \$37.91 | | 2012 | 5 | \$50.18 | | 2013 | 6 | \$54.50 | | 2014 | 7 | \$66.00 | | 2015 | 8 | \$75.99 | | 2016 | 9 | \$90.27 | | 2017 | 10 | \$110.86 | ### Explanation: This table lists the annual revenue in billions of dollars for a company over a ten-year period, from 2008 to 2017. Each row represents a year and its corresponding period, showing the increasing trend in revenue, which nearly doubles over this decade.
