Question

oncern over the weather associated with El Nino has increased interest in the possib ty that the climate on earth is getling warmer. The most common theory relates an increase in atmospheric levels of carbon dioxide(CO2 greenhouse gas, to increases n temperature. A regression analysis of the mean annual Co conoentration (in parts per million) in the atmosphere at the top of Mauna Loa in Hawali and the mean annual air temperature (in degrees Celsius) ove both land and sea across the globe for 37 ears was performed. Assume all conditions are met for simple linear regression inference. In words, what is the ccrrect alternative hypothesis to test the theory proposed in this problem? Click the icon to views the regression analysis. hoose the correct answer below A. Amwal CO2 ! 1s over Mauna Loa do not help explan annual average global air temperature. B. Annual average global air temperatures do not help explain annual CO2 levels over Mauna Loa C. Annual CO2 leves over Mauna Loa do help explain annual average global air temperature D. Annal average global air temperatures do help explain annual CO2 levels over Mauna Loa.

Explanation / Answer

Here from the given table of variables of the regression analysis, we can see that CO2 is an independent variable. The alternate hypothesis is always the research hypothesis that is that the independent variable here is able to explain the variation in the dependent variable. Therefore the independent variable CO2 do help explain the variance in the dependent variable and therefore c is the correct answer here.
