(Solved): b Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever ...

Levels of carbon dioxide $$\left({\mathrm{CO}}_2\right)$$ in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800 , before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now over $$400\mathrm{ppm}$$. The table below shows the rapid rise of $${\mathrm{CO}}_2$$ concentrations over the 55 years from $$1960?2015$$, also available in CarbonDioxide., We can use this information to predict $${\mathrm{CO}}_2$$ levels in different years. (a) What is the explanatory variable? What is the response variable? $${\mathrm{CO}}_2$$ concentration is the explanatory variable and Year is the response variable. Year is the explanatory variable and $${\mathrm{CO}}_2$$ concentration is the response variable. eTextbook and Media (b) Use technology to find the correlation between year and $${\mathrm{CO}}_2$$ levels. Round your answer to three decimal places. (c) Use technology to calculate the regression line to predict $${\mathrm{CO}}_2$$ from year. Round your answer for the intercept to one decimal place and your answer for the slope to three decimal places. $${\widehat{CO}}_2=$$ eTextbook and Media (d) Interpret the slope of the regression line, in terms of carbon dioxide concentrations. The slope tells the predicted number of years for the $${\mathrm{CO}}_2$$ level to go up by one. The slope tells the predicted number of years for the $${\mathrm{CO}}_2$$ level to go up by that amount. The slope tells the predicted change in $${\mathrm{CO}}_2$$ level one year later. The slope tells the predicted $${\mathrm{CO}}_2$$ level one year later. (e) What is the intercept of the line? Round your answer to one decimal place. The intercept is Does it make sense in context? eTextbook and Media (f) Use the regression line to predict the $${\mathrm{CO}}_2$$ level in 2003. Use rounded slope and the intercept from part (c), then round your answer to one decimal place. $${\mathrm{CO}}_2$$ level in $$2003=$$ Use the regression line to predict the $${\mathrm{CO}}_2$$ level in 2025. Use rounded slope and the intercept from part (c). then round your answer to one decimal place. $${\mathrm{CO}}_2$$ level in $$2025=$$ Use the regression line to predict the $${\mathrm{CO}}_2$$ level in 2025. Use rounded slope and the intercept from part (c), then round your answer to one decimal place. $${\mathrm{CO}}_2$$ level in $$2025=$$ eTextbook and Media (g) Find the residual for 2010. Use rounded slope and the intercept from part (c), then round your answer to two decimal places. Residual for $$2010=$$
