Data was collected for 300 fish from the North Atlantic. The length of the fish (in mm) is summarized in the grouped frequency distribution table below. Lengths (mm) Frequency 140 - 1431144 - 14716148 - 15171152 - 155108156 - 15983160 - 16318164 - 1673What is the class boundary between the fifth and sixth classes?class boundary =

Sagot :

Solution:

From the given data, the class boundary between the fifth and sixth classes is thus evaluated as follows:

step 1: Determine the upper class limit of the fifth class.

The upper class limit of the fifth class is

[tex]159[/tex]

step 2: Determine the lower class limit of the sixth class.

The lower class limit of the sixtth class is

[tex]160[/tex]

step 3: Evaluate the class boundary between the fifth and sixth classes.

Thus, we have
