what is the answer to question 1 and 2

Question 1 10 pts Increase in temperature since 1967 in degrees Celsius and concentration of carbon dioxide [CO2) in parts per million (ppm) were measured from the top of Mauna Loa in Hawaii between 1967 and 2011. Environmental scientists claim that the additional CO2 in the air contribute to the increase in Time global temperatures that have occurred. Alt-mp 18 Mir Does the data indicate an underlying linear relationship between temperature and CO2 concentration? nts What is the response variable in this situation? the intercept O the slope O temperature My Media CO2 concentration Media Question 2 10 pts Increase in temperature since 1967 in degrees Celsius and concentration of carbon dioxide (CO2] in parts per million (ppm) were measured from the top of Mauna Loa in Hawaii between 1967 and 2011. Environmental scientists claim that the additional CO2 in the air contribute to the increase in global temperatures that have occurred. Does the data indicate an underlying linear relationship between temperature and CO2 concentration? What is the null hypothesis? O The means are all equal. The slope is zero O The intercept is zero The distribution of temperature depends on the distribution of CO2
