A. Suppose you select a sample of 530 st.Paulites. show the sampling of p to 4 decimals.

Op = ?

B.based upon a sample of 540 St. Paulites, what is the probability that the sample proportuon will be within 0.03 of the pipulation proportion to the 4 decimal.

Probability?

 

C. Suppose you select a sample of 199 st. Paulites. Show the sampling distribution of p to 4 decimals. E(p)= ?

Op=?

D. Based upon a smaller samply of only 190 St. Paulites, what ia the probabikitt that the sample proportion will be within 0.03 of the pipulation propoetio  to the 4 decimal.

Probability ?

E. As measured by the increase in probabilty , how much do yiu gain in prevision by taking the larger samole in parts a and b rathee than the samllee in parts c and d.
