Problem 1: A study is made of the ages in whole number of years of the dwellers in an apartment complex and the following table was computed:
|
0 to 9
|
15%
|
|
10 to 19
|
25%
|
|
20 to 39
|
35%
|
|
40 to 79
|
25%
|
(Where 0, e.g., means someone is under the age of 1 and where 2, e.g., means someone has completed 2 years and any fraction thereof but not 3 or more years, etc.).
a. Draw a histogram of this data. Be sure to give labeled scales.
b. Use the given table and/or the histogram to answer the following questions:
1. What is the median age of the dwellers in the apartment complex?
2. If there are 20 person in the complex, about how many are 40 or older.
