2) Carbon Dioxide Change As humans continue to burn fossil fuels, the amount of C02 in the atmosphere increases. SCIentIsts measure atmospheric C02 in parts per million (ppm), which means the number of C02 moleCUles for every one million molecules of other atmospheric gases such as oxygen and nitrogen Scientists have been tracking the amount of C02 in the atmosphere at the Mauna Loa Observatory in Hawaii since 1958. The table below shows the CO2 measurements recorded for the years 1959-2018. w . . 1985 346.12 1998 366.70 m- m . . 347. 42 1999 368. 38 393. 85 m_ 1974 330.18 1987 349.19 2000 369. 55 mm _98- 65 www EEI_-_-WEI Em 406- 55 321. 38 1979 336.84 1992 356. 45 379. 80 408- 52 mm 383 9 m\" 360. 82 2008 385. 60 2021 416. 45 36261 zoos 3874s _ 344.65 1997 363.73 2010 (Source: U.S. Department of Commerce/National Oceanic & Atmospheric Administration. htt s: www.esrl.noaa. ov md cc trends data.html ) a) Use these data to make a summary table of the mean C02 level in the atmosphere as measured at the Mauna Loa Observatory for the years 1960, 1965, 1970, 1975, ..., 2015. b) Define the number of years that have passed after 1960 as the predictor variable x, and the mean C02 measurement for a particular year as y. o Create a linear model for the mean C02 level in the atmosphere, y = mx + b, using the data points for 1960 and 2015 (round the slope and y-intercept values to three decimal places). 0 Use Desmos or Excel (directions are included in this assignment) to sketch a scatter plot of the data in your summary table and also to graph the linear model over this plot. 0 Comment on how well the linear model fits the data
