AP Psych Assignment 5.3

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Think about the situation where you are investigating the relationship of study time vs. exam grade.a. Which variable would be on the x-axis (and why)?b. Which variable would be on the y-axis (and why)?c. Would you expect the slope to be positive or negative (and Why)? 2) Contrast and compare interpolation with extrapolation. Which is “safer” to use and why?3) Look up how “the best fit straight line” is constructed. The term “Least squares” should be in your explanation.4) If I plot some data and end up with a r2 of (-) 0.99, is my plot useless? Explain.

Safety is the     responsibility of the TA only.     primary responsibility of everyone in the lab.     last thing to think about when doing lab experiments.     least important thing, basically just trivia for extra credit.     first topic to read about after you do an experiment.

• Stock solution: 1000 mg/L Target sample concentrations: 50-400 mg/L • Create a 5-point standard dilution to cover the test • If each test only needs 10 mL, make plans to make the dilution so you have 20 mL of each concentration. ·

The initial population size was 790 jackelopes. After only 3 year(s), a new count was taken revealing 685 jackelopes. Assuming the population of jackelopes is best modeled with an exponential function, estimate the number of jackelopes in the count taken after a total of 8 years

Which of the statements below are TRUE regarding the mean and standard deviation? I.    As the number of measurements increases, x̄ approaches μ if there is no random error.II.    The square of the standard deviation is the average deviation.III.    The mean is the center of the Gaussian distribution.IV.    The standard deviation measures the width of the Gaussian distribution.

This assignment is designed to help you learn how to determine total costs by combining direct and indirect costs for a particular department. In this GHA, you will be determining the total costs for three departments: (1) Physical Therapy (2) Occupational Therapy and (3) Speech Therapy. To determine the total costs, you will need to add the direct costs to the indirect costs using the template provided below. Please use the example provided in the assignment description if you find that you need some support understanding the required calculations. DIRECT COSTS The direct costs for each department are easily identifiable, because they are the costs that are directly attributable to the department. The direct costs are as follows: Physical Therapy (PT) Occupational Therapy (OT) Speech Therapy (ST) Total Direct Costs INDIRECT COSTS The indirect costs will need to be allocated to Physical Therapy (PT), Occupational Therapy (OT), and Speech Therapy (ST). The indirect costs in this…

For each of the following scenarios, determine if the error will cause the molarity of the hydrochloric acid to be greater than, less than, or the same as the initial value. A: A student adds 50 mL of water to the reaction flask with unknown hydrochloric acid instead of the 25 mL sated in the procedure. B: A student adds 50 mL of water to the reaction flask with unknown hydrochloric acid instead of the 25 mL stated in the procedure. C: A student doesn't notice the some of the HCL has dripped out from the volumetric pipet when transferring to the reaction flask

researchers working in a chemistry lab were examined anatomical structures of the brain using concentrated formaldehyde solutions. Once their studies concluded there remained 1.5 gallons of the substance and the researcher decided to pour this down the drain. In this case, they directly violet regulations put in place by which office?1. Office of research integrity 2. Institutional animal care and use committee3. Occupational safety and health administration 4. Institutional review board
