1. Installing a hypervisor on a computer opens a whole new world of possibilities for exploring various operating systems and networking options. In this project, you download and install VirtualBox, a free hypervisor that is compatible with Windows, Linux, and macOS host operating systems, and then you create a VM. In the next project, you’ll assign Linux on the VM. Complete the following steps on a Windows 10/8/7 computer.
   1. If you’re using VirtualBox as your hypervisor, confirm that Hyper-V is not enabled. Right-click Start and click Apps and Features. Scroll down to the bottom of this window and click Programs and Features. In the left pane, click Turn Windows features on or off. Make sure Hyper-V is unchecked and click OK. Not all Windows computers list Hyper-V as an option.
   2. Go to the Oracle VirtualBox website (virtualbox.org) and download and install VirtualBox on your computer.
   3. To set up a new virtual machine, open VirtualBox and click New at the top of the VirtualBox window. The “Create Virtual Machine” window appears.
   4. Assign the VM a name, select Linux from the Type drop-down menu, and select Ubuntu (64-bit) from the Version drop-down menu. Click Next.
   5. Set the memory size selection to 4096 MB and click Next.
   6. Be sure that “Create a virtual hard disk now” is checked and click Create. For the hard drive file type, make sure that the default selection VDI (VirtualBox Disk Image) is checked. Click Next.
   7. Be sure the default selection Dynamically allocated is checked so that space on the physical computer’s hard drive is used only when it’s needed by the VM. Click Next. Change the size of the virtual hard drive to 16GB and click Create. When you complete the wizard, the new virtual machine is listed in the left pane of the VirtualBox window.
   8. Don’t start the VM yet, you’ll install Ubuntu Desktop on this VM in the next problem. For now, explore the window’s menus, tools, and options. A snapshot of the VM saves a copy of the VMs disk file and can be used to restore the VM to an earlier state or a clone. How can you make a snapshot of your VM? Take a snapshot and name it Pre-OS snapshot.
   1. To change the boot order of a physical computer, you would enter the motherboard’s BIOS/UEFI setup screen and change the boot order settings. How can you change the boot order for your VM?

A random sample of 40 students taken from a university showed that their mean GPA is 2.94 and the standard deviation of their GPAs is .30. Construct a 99% confidence interval for the mean GPA of all students at this university

What would you suggest as an effective policy to reduce firearms violence in the school setting, either among students or those attacking students? Throughly explain why your policy would work.

Studies show that 10% of the population is left-handed. In a study with 186 students, only 16 were left-handed. Does this suggest that left-handed students are underrepresented in this study? Use α = 0.1.

Suppose a university significantly increases tuition. Which group of students would have a greater elasticity of demand for acquiring their degree from this particular institution; students just entering their first semester of college or students approaching graduation?

You must use the concept of elasticity to explain your answer. Explain your answer with appropriate detail.

• Providing a substantive response of not less than 75 words.
• Applying economic concepts when applicable.

The number of pizzas consumed per month by university students is normally distributed with a mean of 8 and a standard deviation of 2. Use Excel to answer the following questions:

A. What proportion of students consume more than 11 pizzas per month?

Probability =

B. What is the probability that in a random sample of size 8, a total of more than 80 pizzas are consumed? (Hint: What is the mean number of pizzas consumed by the sample of 8 students?)

Probability =
