Answer:
4.0486
Step-by-step explanation:
The margin of error is calculated using [tex]E=z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} }[/tex]
Where n=60 is the sample size and [tex]\sigma=16[/tex] is the population standard deviation.
The critical value corresponding to 95% confidence interval is [tex]z_{\frac{\alpha}{2}}=1.96[/tex]
We substitute the values to obtain;
[tex]E=1.96*\frac{16}{\sqrt{60} }[/tex]
[tex]E=1.96*2.06559=4.0486[/tex]
