Answer:
Answer : (0.1183 ≤ p ≤ 0.3103)
Step-by-step explanation:
Solution :
Given that,
a) n = 70
x = 15
Point estimate = sample proportion (p)= x / n = 15 / 70 = 0.2143
1 - p = 1 - 0.2143 = 0.7857
At 95% confidence level
α = 1 - 95%
α =1 - 0.95 =0.05
α/2 = 0.025
Zα/2 = Z0.025 = 1.960
Margin of error = E = Zα / 2 * √ (( p * (1 - p )) / n)
= 1.96 (√((0.2143 * 0.7857) / 70)
= 0.096
A 95% confidence interval for population proportion p is ,
P - E ≤ p ≤ P + E
0.2143 - 0.096 ≤p ≤ 0.2143 + 0.096
(0.1183 ≤ p ≤ 0.3103)
