Answer:
580.
Step-by-step explanation:
The provided information are:
Population mean [tex](\mu)[/tex] = 500
Population standard deviation [tex](\sigma)[/tex] = 40
z-score = 2
The formula to calculate the z-score is:
[tex]z=\frac{x-\mu}{\sigma} \\[/tex]
x = data item.
The data item can be computed as:
[tex]2=\frac{x-500}{40} \\\\80=x-500\\x=580[/tex]
Hence, the data item is 580.
