Answer:
[22.57 ± 2.776]
Step-by-step explanation:
Hello!
You have the 95% Confidence Z-interval (21.182;23.958), the mean X[bar]= 22.57 and the sample size n=25.
The formula for the Z interval is
[X[bar] ±
]
The value of Z comes from tha standard normal table:
![Z_{1-\alpha /2} = Z_{0.975}= 1.96](https://tex.z-dn.net/?f=Z_%7B1-%5Calpha%20%2F2%7D%20%3D%20Z_%7B0.975%7D%3D%201.96)
The semiamplitude (d) or margin of error (E) of the interval is:
E or d= (Upperbond- Lowerbond)/2 = (23.958-21.182)/2 = 2.776
[X[bar] ± E]
[22.57 ± 2.776]
I hope it helps!
