To find this out you need to be clear about who.
Thus 186 sample size arrived at should be corrected adjusted for finite population. Assuming this is the normal distribution let us find the Z value from the Z table. As such the determination of the appropriate sample size is one of the recurrent problems in statistical analysis. To find this out you need to be clear about who.
