Consider the following frequency distribution. Class Frequency 12 up to 15 3 15 up to 18 6 18 up to 21 3 21 up to 24 4 24 up to 27 4 The total number of observations in the frequency distribution is ______.

Respuesta :

The total number of observations in the frequency distribution = 20

Step-by-step explanation:

The given table from the given data:

Class:            12 - 15   15 - 18   18 - 21   21 - 24   24 - 27

Frequency:   3            6            3           4            4

To find, the total number of observations in the frequency distribution is __________ .

Class:                 12 - 15   15 - 18   18 - 21   21 - 24   24 - 27

Frequency:         3            6            3           4            4

Cumuative

frequency (CF):   3             9           12          16           16

The total number of observations in the frequency distribution = 20
