Answer:
0.625± 1.645*0.0571
Step-by-step explanation:
First calculate the estimate as 72 petty cases and 45 are unsolved as follows :
estimate :72/45=0.625
the critical value is given by cumulative probability equal to the p* (critical probability) as ,
1)compute value for alpha =1-(confidence value /100).
=1-(90/100)=0.1
for critical probability as p*=1 - (alpha/2)=1 -(0.1/2)=0.95
for this critical value is denoted to central area ,
Z(alpha)=1.645
now the standard error :
s= here p is estimate and q is probability of failure and n is total no of cases
s= =0.0571.
