Suppose users share a 3 Mbps link. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 20 percent of the time, suppose packet switching is used and there are 4x225-900 users. 1. Find the probability that the number of users transmitting simultaneously is from 156 to 204 Or P (156< x < 204)-? 2. Find the probability that there are at least 204 users transmitting simultaneously Px> 204)? 3. Find the probability that there are less than 156 users transmitting simultaneously P(x< 156)?

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
