What percentage of the general U.S. population has bachelor’s degrees? Suppose that the Statistical Abstract of the United States, 120th Edition, gives the following percentage of bachelor’s degrees by state. For convenience, the data are sorted in increasing order.
19 20 20 20 21 22 22 22 23 23
23 23 23 24 24 24 24 24 25 25
26 26 26 26 26 27 27 27 27 28
28 28 28 28 28 29 29 29 30 30
30 31 31 33 33 34 34 36 37 40
Add those numbers and divide by 50 to find the average.

To calculate the percentage of the general U.S. population with bachelor's degrees, we need to find the average of the percentages given for each state.
First, add up all the percentages:
19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 23 + 23 + 23 + 24 + 24 + 24 + 24 + 24 + 25 + 25 + 26 + 26 + 26 + 26 + 26 + 27 + 27 + 27 + 27 + 28 + 28 + 28 + 28 + 28 + 29 + 29 + 29 + 30 + 30 + 30 + 31 + 31 + 33 + 33 + 34 + 34 + 36 + 37 + 40 = 1351.
Next, divide the sum by the number of data points (in this case, 48) to get the average percentage:
1351 / 48 = 28.1458.
Therefore, the average percentage of bachelor's degrees in the general U.S. population is approximately 28.15%.
To find the percentage of the general U.S. population with bachelor's degrees, we need to calculate the median of the data provided. The median represents the middle value when the data is sorted in increasing order.
Sorting the data:
19 20 20 20 21 22 22 22 23 23
23 23 23 24 24 24 24 24 25 25
26 26 26 26 26 27 27 27 27 28
28 28 28 28 28 29 29 29 30 30
30 31 31 33 33 34 34 36 37 40
The median is the middle value of the sorted data, which in this case is the 25th value. So, the median is 26.
Therefore, we can say that approximately 26% of the general U.S. population has bachelor's degrees.
