Answer:
(-3, 19)
Step-by-step explanation:
Answer:
Margin of error = 0.09
Confidence interval = (0.29, 0.41)
Step-by-step explanation:
Sample size, n = 1023
p = 38%
= 0.38
Standard deviation, σ = 1.5
Consider the level of confidence to be 95%
So, corresponding z* value for 95% confidence level = 1.96
![\text{Now, Margin of error = }z^*\times \frac{\sigma}{\sqrt{n}}\\\\\text{Margin of error = }1.96\times \frac{1.5}{\sqrt{1023}}\\\\\textbf{Margin of error = }\bf 0.09](https://tex.z-dn.net/?f=%5Ctext%7BNow%2C%20Margin%20of%20error%20%3D%20%7Dz%5E%2A%5Ctimes%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%5Ctext%7BMargin%20of%20error%20%3D%20%7D1.96%5Ctimes%20%5Cfrac%7B1.5%7D%7B%5Csqrt%7B1023%7D%7D%5C%5C%5C%5C%5Ctextbf%7BMargin%20of%20error%20%3D%20%7D%5Cbf%200.09)
Hence, confidence interval = p ± margin of error
= 0.38 ± 0.09
= (0.29, 0.47)
