2 Question # A digitized video-transmission involves streaming of packets wherein the statistics of occurrence of bit-rate from packet-to-packet may strongly depend in values between consequent packets involved; and, this bit-rate (denoting the RV) is considered as of variable bit rate (VBR) type Suppose a test digitized transmission carries a randomly mixed set of such video packets. The statistics of occurrence the packets are designated in 10 groups. The number of occurrences of each group and the corresponding random value of the associated random bit rates (R, in Mbps) depicting the RVs in each group are as follows: Index of the events/groupsi 2i 3 i 4i 5 6 i7i 8 i9 i 10 enumerated Associated RV: 6.4 5.9 0.6 6.2 5.7 6.16.35.7 5.6 0.2 Video Bit rate (R) Packets in Mbps Number of occurrences (n,) 85 | 65 | 55 | 40 | 45 | 60 | 70 | 35 | 30 | 25 Determine the following of the RV (Bit rate: Ri in Mbps): I. Find the upper and lower-bounds of the average performance of the RV II. State with reason the most appropriate mean value (AM. HM or GM) III. IV. that describes the average performance of the bit rate Find the expected mean, median, mode, variance and standard deviation Plot the cumulative probability distribution (CDF) of the RV. [Answer-hints: Median-5.8 Mbps; ơ-2.049 Mbps!
