In a particular year, 68% of online courses taught at a system of community colleges were taught by full-time faculty. To test if 68% also represents a particular state's percent for full-time faculty teaching the online classes, a particular community college from that state was randomly selected for comparison. In that same year, 31 of the 44 online courses at this particular community college were taught by full-time faculty. Conduct a hypothesis test at the 5% level to determine if 68% represents the state in question.

Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
(A). In words, state what your random variable P' represents.
(B). State the distribution to use for the test. (Round your standard deviation to four decimal places.)
P' ~ ____ ( ____ , ____ ).
(C). What is the test statistic? (Round your answer to two decimal places.)
t = _____.
(D). What is the p-value? (Round your answer to four decimal places.) Explain what the p-value means for this problem.
(E). Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value.
(F). Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and write an appropriate conclusion.
(i) Alpha:
(ii) Decision:
(iii) Reason for decision:
(iv) Conclusion:
(G) Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.)

From the six categories that you read about this week, share with your colleagues a case that presented to you in your practicum (or a personal experience). Describe how the skin disorder developed and what treatment was prescribed. Explain the cause of the skin disorder (bacterial, fungal, etc.), but focus on the treatment. Include pharmacodynamics, pharmacokinetics, and pharmacotherapeutics of the medication prescribed (you may have to use an additional resource like Lexicomp, UpToDate, or Epocrates). Don’t forget monitoring and patient education.

1. State and Explain how each of these errors would affect (high, low, no change) your calculated values of solubility and Ksp.

a) The saturated solution of Cu(IO3)2 is not filtered to remove undissolved Cu(IO3)2.

b) The saturated solution of Cu(IO3)2 is filtered into a wet flask.

c) You use only 5.00 mL of the saturated solution instead of 10.00 mL.

2. At the end point of a titration in the standardization of the Na2S2O3 solution (using KIO3), you have a colorless (and clear) solution. At the end point in the determination of Cu(IO3)2 solubility, you have a colorless (but cloudy) heterogeneous mixture. Explain this difference. (Hint: look at the reaction equations on the first page of the handout.)

  1. State whether the following statement is true or false and explain your reasoning.

Protein tyrosine phosphatases display exquisite specificity for their substrates, unlike most serine/threonine protein phosphatases, which have rather broad specificity.

BioChemistry Problem

State whether the Hill Coefficient (N) is positive or negative? Explain your reasoning in each case.

(a) The protein has multiple subunits, each with a single ligand-binding site. Binding of ligand to one site increases the binding affinity of other sites for the ligand.

(b) The protein is a single polypeptide with two ligand-binding sites, site one causes a structural change that decreases affinity for the second ligand.

(c) A molecule binds to a protein and inhibits binding of the natural ligand.

(d) The protein has two subunits and as one ligand binds, the second binds with lower affinity.

(Each answer is expected to be detailed in the physiology of the macro and micro anatomy.)

A: You are sitting at your place of work, on the third story of the building, with the time

being approximately 1:15pm. You just returned from your lunch hour, in which you met

your family at a local restaurant and enjoy a nice meal. You family, spouse and two

children, were then on their way to go shopping while you had a 1:30pm meeting with

your team.

At 1:31pm you head in the conference room and take a seat next to the window along

the back way, facing the only door to the room. You are surrounded with 12 other

individuals when the room begins to shake. The shaking becomes more intense and lasts

for 45 seconds. Explain in detail, what is occurring in your body.

B: Explain what was occurring in your body at 1:15-1:30pm.

Case Study:

Retirement can’t come soon enough for Dylan Rainelli. After 35 years of selling specialized agriculture equipment to the region’s custom harvesters, he’s ready to spend his days in fishing on Burr Lake.

Dylan’s handled many large and high-dollar accounts throughout his years at Red Star Farm Equipment, but none larger than his account with Matlock Harvesting. Matlock Harvesting is a full-service custom harvesting company whose clients span the entire Midwest. Matlock’s equipment replacement cycle yields Red Star Farm Equipment 10 million annually-- all brokered by Dylan. Dylan believes the experience he has gained throughout his career and his commitment to servicing his accounts has been an important factor in keeping loyal customers - especially Matlock Harvesting. It’s important to Red Star Farm Equipment that Dylan’s successor provide this same level of commitment to these accounts as well.

Red Star Farm Equipment recently participated in a Penn State Career Fair with the goal of finding upcoming graduates to fill several positions in various departments within their company. You are well aware of the experience a sales career with Red Star Farm Equipment can provide and are excited to meet with their representatives. After the Career Fair, you receive an official interview at the company headquarters. They mention you are being considered as Dylan’s replacement and stress the importance and value that his accounts are to the company. You are asked two questions that you know will make or break the interview: what steps you will take to maintain these accounts? How will you continue to keep these accounts as long-term clients? How do you respond?

You will design and implement a graphics program that draws four concentric rectangles in a window, using four different colors of your choice, meeting the following specifications.

• The size of the window is determined by the user of the program. To be specific, you should prompt the user for both the width and height of the window (in pixels), and then you should set the size of the window using these values. (Hint: use the setup() method of the window.) Make the largest colored rectangle by setting the background color of the window. The three other colored rectangles will be drawn using the draw_rectangle() function described below in Program Design.

• After the first rectangle, the size of each rectangle will be half of the size of the one before it. Using the rectangles shown in the graphic as an example, the length and width of the red rectangle are half of the length and width of the blue rectangle, respectively. Then the length and width of the yellow rectangle are half of the length and width of the red rectangle, respectively, etc.

• You should use a for loop to draw the three rectangles. Because of this, only one line of code in your program should have a call to the function draw_rectangle().

Use meaningful variable names.

Use horizontal and vertical white space reasonably and consistently.

Use named constants as appropriate.

Program Design Your program is to be implemented using the function draw_rectangle(), which draws a rectangle centered in the window of a specified size and color. In order to do this, start your program with exactly the following lines of codes: import turtle import sys sys.setExecutionLimit(60000) # 60 seconds def draw_rectangle(turt, width, height, color): turt.pencolor(color) turt.fillcolor(color) turt.up() x = - width / 2 y = height / 2 turt.goto(x,y) turt.down() turt.begin_fill() # Draw the top turt.setheading(0) turt.forward(width) # Draw the right side turt.right(90) turt.forward(height) # Draw the bottom turt.right(90) turt.forward(width) # Draw the left side turt.right(90) turt.forward(height) turt.end_fill() # Your code goes here

Please explain every step clearly and thoroughly in python, my python code keeps giving an error message.
