Math, statistics... How to I make a frequency distribution with this?

Just answer the frequency distribution. Once I know that, I can do the rest on my own.

    Create your classes starting at 35000 and a width of 5000 per class.

    35000 ≤ x < 40000

    40000 ≤ x < 45000

    45000 ≤ x < 50000

    50000 ≤ x < 55000

    55000 ≤ x < 60000

    60000 ≤ x < 65000

    65000 ≤ x < 70000

    70000 ≤ x < 75000

    PART A:

    Now for each median household income for the 50 states + DC, add a tally mark for the appropriate class. For example, 39,622 would go in the first class. At the end, add up how many values are in each class.

    The table with 8 classes with numbers next to them become your frequency distribution.

    PART B:

    Now turn the numbers into a percent. There are 51 total values, so divide each tally by 51 and then write it as a percent.

    For example:

    If you had 3 in a specific class:

    3/51 = 1/17 = 0.05882 ≈ 5.9%

    Write down each of the classes and instead of the absolute number, put the percentage. You have a *relative* frequency distribution.

    PART C:

    Turn the result from A into a histogram (a bar chart)

    PART D:

    Turn the result from B into a histogram (a bar chart, but with percentages instead of absolute frequency counts).
