NOTE: Even thought the data is grouped, the random variable is still discrete because the sample space only includes values to the hundredths place. Sample space: {$0.00, $0.01, $0.02, $0.03, ...} We know this is a probability distribution because it states that it is the "% of global population by income." Let's create a probability distribution table to organize the data to use to find the means and standard deviations for the years 2001 and 2011. You will find the quantitative values for the classes in the small print under the graph. The high income category includes $50.01 and up. For our purposes, we will end that category at $100. Please complete the table. Round the midpoints to the nearest dollar. Do not use spaces in your answers. P(2001) P(2011) Classification I = Income in $/Day Midpoint (use decimals) (use decimals) Poor 0-2 0.29 0.15 Finis Low Income AC 0.50 Middle Income 10.01-20 0.07 0.13 Upper-Middle Income 0.09 High Income 50.01-100 0.06 0.07 Use technology (graphing calculator, Excel, or Google Sheets) to find the mean and standard deviation.. If you use a graphing calculator, you will type the data into L1, L2, and L3, Be sure to specify which two lists to use when finding the 1 Variable Statistics. Round to the nearest hundredth. 2001 2011 What can we tell from the means and standard deviations? The average daily income for people in 2001 was $ and the average daily income in 2011 was S The average daily income from 2001 to 2011 by almost The standard deviation a very small amount indicating a little variation in the 2011 individual data.
