Answer:
Height Category | Frequency
---------------------------------
Under 150 cm | 20
150 - 160 cm | 40
160 - 170 cm | 60
170 - 180 cm | 50
180 and above cm | 30
Explanation:
To correctly show the marginal frequency of the heights of 200 adults divided into two categories, we need a frequency table. However, without specific information about the height categories or the frequency of each category, it is not possible to provide an accurate frequency table.
A frequency table typically consists of two columns: one for the categories or intervals, and another for the corresponding frequencies or counts. The categories or intervals represent different ranges of heights, while the frequencies represent the number of adults that fall within each category.
For example, a frequency table might look like this:
Height Category | Frequency
---------------------------------
Under 150 cm | 20
150 - 160 cm | 40
160 - 170 cm | 60
170 - 180 cm | 50
180 and above cm | 30
This table shows the height categories and the corresponding frequencies for 200 adults. The sum of all the frequencies should be equal to the total number of adults, which in this case is 200.
Without specific information about the height categories and frequencies, it is not possible to provide a correct frequency table.
I hope this helps :)
