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
The correct answer is D
H0 : annual average global temperatures do not help explain annual co2 levels over mauna loa
H1 : annual average global temperatures do help explain annual co2 levels over mauna loa
as this is the claim we are interested in.
