Hi, I need your help. I used the Slovins formula to calculate the sample size from the population of 1st-year college students (319)

n=319/1+319 (0.05)

=177

And I used Stratified random sampling to calculate the sample in each stratum (refer to the attached picture)

Questions:

1. Does it right to use slovin's (non-parametric) and at the same time use Stratified (parametric)? Explain.

2. Kindly refer to the attached picture and tell me if my calculation using the stratified formula in (sample in each stratum) is right. If not, correct it and explain why.

Thank you!
