An urn contains an unknown proportion of red and white marbles

9.30      An urn contains an unknown proportion of red and white marbles. A  random  sample of 60 marbles selected with replacement from the urn showed that 70% were red. Find the (a) 95%, (h) 99%, and (c)  99.73% confidence limits for the actual proportion of red marbles in the urn. Present the results from using both the approximate formula and the more exact formula of Problem 9.12. 

 

9.31       How large a sample of marbles should one take in Problem  9.30 in order to be (a) 95%, (h) 99%; and  (c) 99.73% confident that the true proportion does not differ from the sample proportion by more than 5%?
