Answer 1

Answer:

Given that:

Find the minimum sample size n needed to estimate p for the given values of c, $\sigma$, and E

c=0.98, $\sigma$ =5.4, and E=2

Here we are given

c = 0.98 , $\sigma$ = 5.4 , E =2

Here  

Zc Z1-0.02/2 2.33

The required sample size is given by

  

(Zc*a/EY n=

  

(2.33 5.4/2)2 n=

  

n (12.582/2)2

  

n=(6.291)2
