analysis for research

Job ID: 34108121

Budget: $10 – $30 USD

I need someone to help me calculate the sample size as fewer as possible.

with an unknown population it is 385 which is high and hard to get
so I need it to be less than 300 and with in confidence level of 95-99 %

previous research in the literature, two studies were done with the same methodology their samples were (328) and (384)

I need a fewer sample size
written and explained clearly so I can convince the IRB committee
