Hi Everyone. Am having a problem on how to get this information from Minitab if you have it installed in your pc. You can use other program, but be specific please. thanks guys.
  1. Use the sample dataset supplied in “US emissions of greenhouse gases.xls” file to solve these.
    1. Calculate the descriptive statistics (Mean, Standard Deviation, Quartiles) for the total amount of greenhouses gases emitted in between years “1996-2009”
    2. Construct a histogram for the distribution of the total amount of greenhouses gases emitted in years between “1996-2009”
    3. Comment on any possible outliers.
    4. Comment on the normality of the data.



Here is the dataGiggle)
