Answer 1

Answer:No,random sampling technique will not fit this scenario.A stratified sampling technique will be more appropriate.

Step-by-step explanation:

The random sampling technique is basically used when datas to be selected such that all members of the population has an equal chances of being selected.so any random pick is taken as a representative of the sample.

When categorization is required,then stratified sampling technique is more appropriate i.e the sample are picked careful ly from the two homogeneous classes as a representative of the sample .
