The number of bytes downloaded per second on an
Chapter 2, Problem 18E(choose chapter or problem)
The number of bytes downloaded per second on an information channel has mean \(10^5\) and standard deviation \(10^4\). Among the factors influencing the rate is congestion, which produces alternating periods of faster and slower transmission. Let represent the number of bytes downloaded in a randomly chosen five-second period.
a. Is it reasonable to assume that \(\mu_{X}=5 \times 10^{5}\)? Explain.
b. Is it reasonable to assume that \(\sigma_{X}=\sqrt{5} \times 10^{4}\)? Explain.
