The Earth’s climate is getting warmer. Most climate scientists agree that one imortant cause of the warming is the increase in atmosphere levels of carbon dioxide (CO2), a greenhouse gas. Here is part of a regression in the atmosphere, measured in parts per thousand (ppt), at the top of Mauna Loa in Hawaii and the mean annual air temperature over both land and sea across the globe, in degrees Celsius. The scatterplots and residuals plot indicated that the data were appropriate for inference and the response variable is Temp.R-squared =67.8%s=0.0985 with 29-2=27 degreed of freedomA) Write the equation of the regression lineB) Find the value of the correlation. Is there evidence of an association between co2 level and global temperature?C) Find the t-value and the p-value for the slope. Is there evidence of an association between co2 level and global temperature? What do you now from the correlation?D) Do you think predictions made by this regression will be very accurate? Explain
