Given: Confidence Level = z value = Given: p = Standard Deviation = Error = Confidence level = Z= Solution: E= Substitute the given to the equation. n= Solution: n = pq () n=( Maria needs a sample size of The Mayor needs a sample size of respondentsSolve for the sample size using the slovin's formula 3. Given: N = 100 5. Given: N = 815 Solution: Solution: 100 11= 1+(100 )(0.05)= n= 1+( )(0.05) 100 11 = 11 = 11 = 4. Given: N = 1250 6. Given: N = 320 Solution: Solution: 1250 n = 1+(1250) (0.05)= 1+( )(0.05)2 1250 11 = 11 11 =
