Question

Could you please explain to me how to solve the missing parts in letter I and C. Thanks 

The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon dioxide
emissions. The protocol became enforceable in February 2005. In 2004, the mean carbon dioxide emission
was 4.87 metric tons per capita. Assume the table below contains carbon dioxide emissions from a random
sample of countries from a study last year. Compute a 90% confidence interval to estimate the mean
carbon dioxide emission for all countries last year.
