Question:
Assume that the carbon dioxide emissions in Exercise 32 are normally distributed. Are you more likely to randomly select 1 country with carbon dioxide emissions less than 30 metric tons or to randomly select a sample of 15 countries with mean carbon dioxide emissions less than 30 metric tons? Explain.
Data from exercise 32:
The mean per capita carbon dioxide emissions in 58 industrialized countries over a 22-year period is 25.5 metric tons. A random sample of 44 countries is selected. What is the probability that the mean carbon dioxide emissions for the sample is greater than 28 metric tons? Assume σ = 395.1 metric tons.
