A) Would it be true or false in comparing two population means, a paired test provides more precise results than an unpaired test because the paired test uses a single sample while the unpaired test uses two independent sample

B) Would it be true or false when comparing two population means, if the variations which are unique to each population are very small compared to the variations which are common to both populations, it is reasonable to assume that the population standard deviations are not equal?

C) Would it be true or false the sample distribution of a sample proportion follows a binomial distribution?

D) Would it be true or false as the sample size increases, the sampling distribution of a sample proportion becomes approximately a normal distribution?
