Answer:

The confidence interval is 22.805

Step-by-step explanation:

We have given,

The Z interval (23.305,25.075)  

Mean \bar{x}=23.69

Sample n=30

To find : The confidence interval?

Solution :

We know, The confidence interval is in the format of

\bar{x}-E

E denotes the margin of error,

E=\frac{U-L}{2}

Where, U is the upper limit U=25.075

L is the lower limit L=23.305

E=\frac{25.075-23.305}{2}

E=\frac{1.77}{2}

E=0.885

Substitute the value of E and \bar{x} in the formula,

23.69-0.885

22.805

Therefore, The confidence interval is 22.805
