Students at a residence hall are reporting internet connectivity issues. The university’s network administrator configured the residence hall’s network to provide public IP addresses to all connected devices, but many student devices are receiving private IP addresses due to rogue devices. The network administrator verifies the residence hall’s network is correctly configured and contacts the security administrator for help. Which of the following configurations should the security administrator suggest for implementation? Router ACLs BPDU guard Flood guard DHCP snooping

7. In a large university (45,000 students) it is known that 71% of the students live on campus. a) If we considered samples of 200 students, describe the sampling distribution of the sample proportion of students who live on campus. (Hint – we said there were three things you needed to mention in a full description, and there is check you must perform to be able to describe one of those 3 things!)

It has been seen that the mean grade point average for students who live on campus is 2.75 with standard deviation of 0.43, while that of students who live off campus is 2.6 with standard deviation of 0.68. 7 sophomores are randomly selected from campus dormitories at a college and 20 sophomores are randomly selected from students who live off campus. The mean grade point averages of the two groups are compared. The expected difference in the sample grade point...

Estimate your average commute time from your residence to school in minutes. Let this estimated commute time in minutes (30) represent the population mean (μ), and assume a standard deviation (σ) of 7.51 minutes. Then, find the probability for the following scenarios. What is the probability that your commute time is less than 15 minutes? What is the probability that your commute time is greater than 35 minutes? What is the probability that your commute time is between 15 minutes...
