Deascribe the sampling distribution of the sample proportion? A )the sampling distribution of the sample proportion for a simple random sample of size n = 167. the proportion with a specified characteristic is p=0.01. Assume that the size of the population is 1,267 B)  the sampling distribution of the sample for a simple random sample n=56. the proportion with a specified characteristic is P= 0.55. assue that the size of the population is 10,4551
