histogram of 1000 counties. Frequency of bachelor's degree on y-axis, bachelor's degree on x-axis. y-axis has scale 0 to 300 in increments of 50. x-axis has scale 0 to 80 in increments of 10. 0-5 is 2. 5-10 is 82. 10-15 is 291. 15-20 is 291. 20-25 is 140. 25-30 is 82. 30-35 is 49. 35-40 is 26. 40-45 is 13. 45-50 is 10. 50-55 is 7. 55-60 is 5. 60-65 is 2. (b) How many data values are within 2 standard deviations (10%) from the mean (20%)? First, find the lower value. The mean minus 2 standard deviations is equal to 20 %. Wrong Solution Solution 20% - 2 * 10% = 0% Next, find the upper value. What percentage of the counties in this sample have between 0% and 40% of its adults having a bachelor's degree or higher?
