Question

1)  recreate the table below, which is part of the output shown above, though it doesn’t show any values. Based on your calculations in previous parts of question 1, fill in the missing values that are indicated with question marks.

2) Based on the slope of the linear regression model, calculate a 95% confidence interval for the change in expected Arctic sea ice coverage for an increase in CO2 by 10 ppm. SHOW ALL STEPS.

3) Calculate a 95% confidence interval for the mean Arctic sea ice coverage for 400 ppm of atmospheric CO2. SHOW ALL STEPS.

(Arctic sea ice' co.)-B.pCo.

Explanation / Answer

1.
R = sqrt(8.261 / 14.1720) = 0.7635

R-sq = 8.261 / 14.1720= 0.5829

Standard Error = sqrt [(14.1720 - 8.2610) / 18] = 0.5731
