Hi$,$ can you help me with this assignment? Thank you in advance

The following measurements were collected from a Web server over a period of $24$ hours:

$$ Average customer response time: $500$ ms

$$ Average number of customers in the system: $500$

$$ Average think time: $5$ seconds

$$ Average disk utilization $($single disk$)$: $50\%$

$$ Average number of visits to disk per customer completion: $1\mathrm{.}1$

$$ Average disk service time: $10$ ms

Are these measurements correct?
