Use StatTools to generate information to help you summarize the data. a. Numerically: Determine the count, the mean growth, the standard deviation of growth, the 5-number summary of growth, and the IQR (inter-quartile range) of growth for the Asian countries and for the Eastern European countries. (See the General Instructions document for help.) Growth (Asia) Growth (EastEurope) One Variable Summary Data Set #1 Data Set #1 Mean 4.725 0.708 Std. Dev. 2.049 5.174 Median 4.200 1.200 Minimum 1.300 -12.100 Maximum 8.800 7.000 Count 12 13 1st Quartile 2.900 -1.650 3rd Quartile 5.900 3.650 Interquartile Range 3.000 5.300 b. Graphically: Create a box plot of the growth data for each of Asia and Eastern Europe. (See the General Instructions document for help.)

The median for the East European countries is also slightly to the right of the true middle of the box (marked
