A wide loaded area carries a net uniformly distributed
pressure q = 150 kPa on a soil profile that consists of 3 layers [4
m sand (20 kN/m³) over 2 m clay (18 kN/m³) over 3. m sand]. The
water table is at the top of clay layer. The permeability of sand
is very large. Cv = 0.50 m2/year; Calpha= 0.05; eo = 1.00. Compute
the settlement due to secondary compression after 60 years.

Suppose you are working in an organization that encourages
employees to participate in workshops and seminars for professional
development. You are responsible for approving reimbursement
expenses. To participate in this activity, employees must travel
away from the organization, spend a few days, spend money from
their pockets, and then turn in a report to get reimbursement for
expenses. For employees, it is sometimes easy to let the numbers
slip a little if the guidelines for on-the-road expenditures in the
organization...

4. A scientist is trying testing the efficacy of a new drug,
NuDrug. He is using the following hypotheses: H0 : NuDrug is
ineffective vs. Ha : NuDrug is effective.
He collects some data and obtains a P-value of 0.0026 for this
test. What is the correct interpretation of the P-value?

A sealed tank holds water to a depth of 2.68 m.Above the water

A drug response curve describes the level of medication in the
bloodstream after a drug is administered. A surge function S(t) =
Atpe−kt (where t > 0) is often used to model the response curve,
reflecting an initial surge in the drug level and then a more
gradual decline. If, for a particular drug, A = 0.03, p = 4, k =
0.03, and t is measured in minutes, estimate the times t
corresponding to the inflection points. (Round your...

Researchers designed an experiment to study the effects of
caffeine withdrawal. They recruited 11 volunteers who were
diagnosed as being caffeine dependent to serve as subjects. Each
subject was barred from coffee, colas, and other substances with
caffeine for the duration of the experiment. During one 2-day
period, subjects took capsules containing their normal caffeine
intake. During another 2-day period, they took placebo capsules.
The order in which subjects took caffeine and the placebo was
randomized. At the end of...

To reduce costs, a medical lab will pool blood to conduct one
single test for the prevalence of a relatively rare disease. Assume
that 25 people had their blood drawn. Since the disease is
relatively rare (only 2 in 100 people have the disease), the lab
takes a portion of each person's blood and pools the blood
together. Then the lab conducts one test of the pooled blood. If
the test is negative, then the lab personnel can conclude that...
