The only answer here can be true.  If you do not understand this question and can’t answer true, please stop and ask Dr G or the LA to help you.  I understand that I should “show my work” for anything that requires a calculation.    I also understand that I am NOT to use formulatext on the test as this is not “showing your work.” 

A vaccine that will require booster shots every ten years is:

The type of organism that has chitin in their cell wall is:

Which of the following is a reason that an antibacterial drug can be selectively toxic against bacteria without affecting human tissue?

A sequence of DNA is AGCTGGATC.  What is its complementary strand?

According to Cohen’s guidelines, what value of d represents a large effect size?Enter your answer as a decimal such as 0.5. HINT: Cohen’s d measures how strong the difference is between two group averages.

When comparing two group means using independent samples, the samples must be related to each other.

A school claims that their average student GPA is exactly 3.0. A researcher wants to test this claim. What is the correct null hypothesis (H₀)? HINT: The null hypothesis always includes the claim being tested. The alternative hypothesis is what the researcher is trying to prove.  

You have forecast the following 24-hour, person-trip, production-attraction (PA) matrices for home-based (HB) and non-home-based (NHB) trip purposes.  Calculate the total number of HB and NHB trips between each zonal pair and in each direction (i.e., originating in zone 1 and destined to 2, originating in 2 and destined to 1, and so on.) over a 24-hour period.  Make reasonable assumptions as needed. NOTE: In your answer space you can insert a 4X4 table and provide your results

The figure below represents a simple network with one origin (O), one destination (D), two internal nodes (1 and 2), and five network links. In this case, the link travel times vary linearly as a function of the flow on the links as shown in the figure.  The demand for travel between the origin and destination is 100 trips. Consider a situation in which 65 vehicles choose route O-1-D (i.e. q1 = q4 = 65) and the rest (i.e., 35 vehicles) choose route O-2-D.  No one chooses O-2-1-D. Show using appropriate calculations that this situation does NOT represent user equilibrium. At equilibrium, will the flow on O-1-D be greater than 65 or lesser than 65? Note that you do not have to solve the equilibrium flows.
