Chapter 10, Problem 11ICA
A bioengineer conducts clinical trials on stressed-out college students to see if a sleep aid will help them fall asleep faster. She begins the study by having 20 students take a sleep aid for seven days and records through biofeedback the time when they fall asleep. To analyze the data, she sets up the following worksheet. Evaluate the expressions that follow; state what will appear in the cell when the command is executed. Column I contains the average time each student took to fall asleep during the seven-day trial. Column J contains any adverse reactions the students experienced (H = headache; N = nausea).
- a. Column K will contain the rating of the time it took the student to fall asleep compared with the control group, who did not take the medication. The statement as it appears in cell K14 is given below. What will appear in cell K14 when this statement is executed?
=IF> (I14>$I$2 + $I$3, ”MORE”, IF (I14 < $I$2 – $I$3, “LESS”,” ”))
- b. Column L groups the participants into three groups according to their reaction to the drug and the time it took them to fall asleep. Assume the statement for part (a) is executed in column K. The statement as it appears in cell L7 is given below. What will appear in cell L7 when this statement is executed?
=IF (AND(K7=”MORE”,J7=”H”), ”'MH”,
IF(AND(K7=”MORE” ,J7=”N”), ”MN”,””)
------
- c. Suppose the formula in column L was changed to regroup the participants. The statement as it appears in cell L9 is given below. In Excel, this statement would appear as a continuous line, but because of space restrictions it is shown here on two lines. What will appear in cell L9 when this statement is executed?
=IF (AND (K7=“MORE” ,OR(J9=“H”, J9=“'N”)), “SEVERE”,
IF (OR (J9=“'H”, J9=“'N”), “'MILD”, IF (K9=“'LESS”,“HELPFUL”,“”))
- d. Suppose the formula in part (c) was copied into cell L 16. What will appear in cell L16 when this statement is executed?
- e.
Suppose the formula in part (c) was copied into cell L 18. What will appear in cell L18 when this statement is executed?

Scenario
You are assigned a role as a mechanical engineer for a vehicle design manufacturing company. Your
department has a software to perform numerical differentiation and integration. To be able to verify the
results of using the software and validate these results, your department manager has asked you to
analytically perform some tasks to validate the results generated by the software.
Q: is the last two digits of your student Id number. If your number is (20110092) then Q=92.
P: is the last digit of your student Id Number. If your number is (20110092) then P=2,
If that digit equals zero then use P=1. Example: If your number is (20110040) then P=1.

For Questions 3 and 4: A cup of water was heated to a
temperature of 90°. It was placed in a refrigerator that had a
temperature of 11°C. The water cooled to a temperature of
17°C in 30 minutes. Let the following variables represent
the relevant quantities.
L = Temperature of the liquid
S= Temperature of the surroundings
t = Time
B = Initial temperature of the liquid (Temperature at t = 0
k = Cooling constant
3. Using the Equation Solver, find the value of k in the
equation L = (B - S)e -kt + S. Remember to set the
equation equal to zero and then enter it into the Solver.

- You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section.

- Hi, I need help with the first part of the problem below because I'm very confused about how P1 and P2 should be calculated. If you look at my notes to solve the problem there is already a formula in place as I always thought the Patm should also be multiplied by the Area in the numerator, but it's not if I look at this specific tutorial solution given by my course but it's not explained why. I have done a while ago a very similar problem with using that formula in my notes and it gave me the right results, but it's not working for this one.
