(a) A host on a cruise ship wants to collect data on the time passengers spend at various activities on board. Which of the following best describes a random sample of passengers? The host assigns each passenger a different number. Using a random number table, he draws 90 of those numbers at random. Then, he selects the passengers assigned to the drawn numbers. Every set of 90 passengers is equally likely to be drawn using the random number table. The host forms 5 groups of passengers based on the levels of the ship that the passengers' cabins are on. Then, he selects 18 passengers at random from each group. The host selects the first 90 passengers who board because these passengers are easily accessible. (b) A city manager wants to poll residents about a park renovation. Which of the following best describes a cluster sample of residents? The city manager uses a computer program to draw 72 residents at random and selects these residents. Every set of 72 residents is equally likely to be drawn by the computer program. The city manager forms groups of 8 residents based on the streets the residents live on. Then, she selects all of the residents in 9 randomly chosen groups. The city manager takes a list of the residents and selects every 3rd resident until 72 residents are selected. (c) A chemist at a pharmaceutical company wants to test the quality of a new batch of microscopes. Which of the following best describes a stratified sample of microscopes? The chemist forms 7 groups of microscopes based on the prices of the microscopes. Then, he selects 8 microscopes at random from each group. The chemist forms groups of 8 microscopes based on the laboratories that the microscopes are in. Then, he randomly chooses 7 groups and selects all of the microscopes in these groups. The chemist takes a list of the microscopes and selects every 7th microscope until 56 microscopes are selected.

The following information is given about an economy's agaregale demand and short-run agyregate supply curves. Using the graph belove, answer the questons that foliow. otentiat GOP (he Yp turve) is eenstant at $600, as shown on the graph. The initial shart-run agoregate supply curve (ASc) is: P=0.1Y the initial agpregate dernand curve (AD0) is: P=105−0.075Y this point.
a) Graph the initial thort-run aggregate supply ( AS0) and aggregate demand (AD0) eurves on the graph above. Solect the curve you want to graph from the drop-down box at the fop of the graph. his point: e) Does any type of gap exist in this scenario? If so, what type of gap and of what amount? (of you docide that no gap exists, leave the "amounf column at o.) d) Suppose that the aggregate demand equation changes to ADt=P=140−0.075Y. Plot this curve on the graph (select the curve tabeled "New Agoregate Demand ( AD1 )" from the drop-down box). depo-down bax at the top of the graph to plot this point. e) Does any type of gap exist in this new scenario? if so, what bpe of gap and of what amount? (ff you docide that no gap exats, leave the "amount" column at 0) Adjusted Equlibrium Point (EQ

For a typical vertebrate cell with a membrane protential of -0.070 V (inside negative), what is the free-energy change. delta G, for transporting 1 mol of Na+ from the cell into the blood at 37 degrees celsius? Assume the Na+ concentration is 12 mM inside the cell 145 mM in blood plasma. Please report your answer to the nearest kilojoule per mole
The case studies are designed to challenge to think strategically at the CIO/CISO level. In your discussion of each question, focus on how you would deal with each of these situations if you were the CIO/CISO thus integrated both your business acumen and your technical knowledge. Students should feel confident exploring any industry trends and should be less concerned about getting "the right" answer. These cases allow you to think about reacting to situations before you are actually put in that situation.
As CIO/CISO, you previously decided to partner with an MDR firm for outside of core hours (9am-5pm, Monday-Friday) support for the blue team that you have built. You now face another decision point which is to build or buy reverse engineering/digital forensics skills on your team.
What are the benefits/draw backs of building reverse engineering skills on your team?
What are the benefits/draw backs of building digital forensics skills on your team?
Discuss any additional considerations that you feel is important.

Step 1 of 3
When the CIO/CISO must decide whether to add reverse engineering and digital forensics expertise to the team or not, it is critical to consider the advantages and disadvantages of each choice.
