This app helped me and gave accurate answers. But there is a problem because only 5% and 10% available margin of error. What if the given margin of error is only 1% or 3%? So the sample size cannot be computed. This type of application is very important especially to semi-college and college students. Please improve this app to make it more helpful. I hope so❤️
