Question
Type "life Expectancy" into Wolfram|Alpha search engine. use the results to answer the following questions. In what year(s) was the data gathered? Which county had the highest life expectancy? How many years? Which county bed the lowest life expectancy? How many years? Select two additional country and the United States and gather the same information: United States life expectancy? life expectancy? life expectancy? Enter the data into the table for each of the countries discussed in #2 - #6 Enter the following statement into Wolfram|Alpha input bar to see the strait line that represents the relationship between life expectancy and literacy rate. Replace the point coordinates with the values from the table in #7, linear fit ((x_1, y_1), (x_2, y_2), (x_3, y_3), ..., (x_n, y_n)} What is the linear relationship between life expectancy vs. literacy rate? What is the slope of the line found in #8? What does this slope imply? Search "life expectancy vs. Literacy" on Wolfram|Alpha to see a scatter plot. Does the scatterptot seem to indicate that people who live in countries with a higher literacy rate also have a higher life expectancy? How well does your equation predict the literacy rate in a 6th country? a. Select another country: b. life expectancy: c. calculated literacy rate (using the equation found in #8): d. Actual literacy rate (from Wolfram|Alpha): Suggestions: Select any two characteristics given by countries and compare them to see if there is a linear relationship between those characteristics. Find and interpret the linear lit of the line. What does the inverse of this function indicate? Give the inverse and define what the slope indicates.Explanation / Answer
