1.The World Bank collects data on many variables related to world development for countries throughout the world. Two of these are internet use, in minutes of users per 100 people, and life expectancy, in years. The data are available in the attached file, INTERNETANDLIFE.CSV.Use the same instructions as in Homework #6 to first upload this file to RStudio Cloud, and then import the file into an RStudio work session using the read.csv command.(1 point)
(1)(3 points) Using R, make a scatter plot with life expectancy as the dependent (Y) variable and internet use as the independent (X) variable. Describe the relationship between these variables.
(2)(2 points) A friend looks at this plot and concludes that using the internet will increase the length of your life. Writea short paragraph explaining why the association seen in the scatter plot does not provide a reason to draw this conclusion.
(3)(3 points) Using R, calculate the correlation coefficient value between life expectancy and internet use. Do you think the correlation is an appropriate way for describing the association between life expectancy and internet use? Why or why not?
