Question

The class intervals 10 to 20 20 to 30 write the class in which 20 is included

Answer 1

Answer:

20-30 is the class interval in which 20 is included.

Step-by-step explanation:

In the statistic,

if the class interval 10-20, it includes 10 to 19 and 20 is excluded

In the class interval 20-30, it includes 20 to 29 and 30 is excluded.

so, the lower limit is included in the class interval but the upper limit is excluded.

20-30 is the class interval in which 20 is included.
