Eo = * MV/m Bo =
2. A computer network experiences 4 disconnections in one minute, 2 in another minute and 7 in another minute. Assume the number N of disconnections in one minute follows a Poisson distribution with parameter Λ, so Pr(N = k) = e −ΛΛ k k! . (a) Given this data, a likelihood function L for the parameter Λ. (b) Find all the critical points of L. (c) Find the maximum likelihood estimator Λ.
Vital Signs: Pulse a) Define pulse. What is the purpose of measuring a pulse? b) On accompanying diagram, mark the various sites for measuring heart rate. What are the two (2) most commonly used sites when measuring heart rate in adults? c) Identify factors that affect pulse rate. Which factors tend to elevate pulse rate? Which factors tend to lower pulse rate? d) State the rationale for assessing the following prior to taking a client’s pulse below: i) emotional and...
Assume the channel bandwidth is 3100 Hz and the maximum data rate is 35 kb/s. To improve the maximum data rate by 60%, how many times should the signal-to-noise-rate (SNR) increase? Based on the improved maximum data rate and SNR, if the SNR further increases by 10 times, can the maximum data rate further increase by 20%?
