Answer 1

The sampling method used here is stratified sampling.

In stratified random sampling we first divide the population in different groups called strata such that there is maximum heterogeneity between different strata and maximum homogeneity within each strata and the we draw sample from each strata.

So, in the above mentioned case also class is divided into two groups on the basis of gender and then sample is drawn from each group or strata.so, this is stratified sampling method.
