Answer #1

The statistic used to estimate, p, the population or process proportion or probability of success is ?

We estimate the population proportion by using the sample proportion p

where p = x / n

x is number of success

n is number of values

So p is sample proportion. which is estimate of population proportion

Answer:- C. pbar, the sample proportion

    A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...
