Answer:
(728, 748)
Step-by-step explanation:
You need the Z value which for 95% confidence interval is 1.96. The mean is $738 and the standard deviation of $41.
[tex]X-Zs/\sqrt{n} \\ X+Zs/\sqrt{n}[/tex]
Therefore we can calculated the confidence interval
[tex]738-1.96\cdot{41}/\sqrt{61} =738-10.3[/tex]
[tex]738±10.3[/tex]
The interval is (728,748)
