Question: An economy studying the link between the total value of a country's exports and that country’s gross Domestic Product or GDP The Economist recorded the GDP and export value in millions for 30 Nations for the same fiscal year the sample data is provided below?
Question: An owner of a large car Loat believe that fuel prices are going to rise significantly and Wonders how this rise might affect demand for the high performance vehicles. Specifically, the owner is investigating a link between how fast a car can go from 0 to 60 mph measured in seconds and the cars economy as measured in miles traveled per gallon used. fast cars which are normally high in demand are associated with higher mpg than there will be much less demand if gas prices rise as predicted. The owner gathered data on 20 vehicles the data is provided below use Excel to calculate the correlation Coefficient r between the two data sets
Question: A team of climatologist civil engineers and automobile engineers are gathering for a conference on climate science where their team is to deliver a keynote address on whether there is a link between fuel efficiency and carbon emissions. fuel efficiency is measured in miles per gallon or mpg and carbon emissions are measured by grams of carbon released into the atmosphere per Mile traveled the data they gathered from 20 different vehicles can be found below use Excel to calculate the correlation Coefficient R between the two data sets round your answer to two decimal places
