what is the difference between oil,mercury and red water on barometer?

Use well labeled diagrams to explain the following two phenomena: the first is that at sunset (or sunrise) the sun appears to be much redder than at mid-day, the second involves the pattern of polarization of the sky when the sun is about to set. Where is the sky most polarized? What orientation is this polarization and why?

Speed Dating Use these female measures of male attractiveness given in Exercise 18 “Speed Dating” in Section 7-2 on page 329: 5, 8, 3, 8, 6, 10, 3, 7, 9, 8, 5, 5, 6, 8, 8, 7, 3, 5, 5, 6, 8, 7, 8, 8, 8, 7. Use the bootstrap method with 1000 bootstrap samples.

1. Construct a 99% confidence interval estimate of the population mean. Is the result dramatically different from the 99% confidence interval found in Exercise 18 in Section 7-2?
2. Construct a 95% confidence interval estimate of the population standard deviation. Is the result dramatically different from the 95% confidence interval found in Exercise 14 “Speed Dating” in Section 7-3 on page 340?

The market structures influence how price and output decisions are made by the firms in their respective structure. In all market structures, one of the primary goals is to maximize profits or minimize losses.

One of the major differences between these market structures is how price and output decisions are made, which in turn depends on the characteristics of each market structure. There are four market structures:

Perfect competition

Monopolistic competition

Oligopoly

Monopoly

Tasks:

Construct a table that describes the various characteristics of each market structure.

Identify a firm for each of these market structures and explain why each firm belongs in the market structure identified.

Using Microsoft Excel, construct a graph for each of the market structures and explain how price and output decisions are made in each structure and how they differ.

How is marginal analysis used in the price and output decisions of firms in the various market structures?

Deliverables:

Prepare a 2-3 page Microsoft Word document that addresses the questions above and meets APA standards.

Include a summary section in your report that contains 5-7 bullet points identifying your major findings or conclusions of your paper.

Submit the summary section as your initial post in the Discussion Area by the due date assigned. Include the full report as an attachment to your posting.

Continue your discussions until the end of the week by commenting on at least two other submissions by your peers, identifying the strengths and weaknesses of each post.

Write every answer in Probability Notation, for example: Event: one marble selected is Red: P(Red) = 12/33 = .3636

For each problem below, we use the following: A bag contains 33 marbles each with a color and a number. 12 Red labeled 1 – 12, 8 blue labeled 1-8, and 13 whites labeled 1-13.

1. A single marble is drawn from the bag:Event:

1. The marble selected is white
2. Event:The marble selected is odd
3. Event: The marble meets both of the above requirements
4. Event:The marble selected is one of the two above (a, b)
5. Event:If we assume it is a white marble, it is also even

2. Three marbles are selected at random from the bag:

1. Event: They are all blue
2. Event: They are all even
3. Event: Exactly 1 blue
4. Event:  at least 1 blue marble is selected

As the school’s test coordinator/statistician, you are tasked with creating a report that includes the following results for Ms. Gibbs:

1. Create a Pareto chart (any other chart is incorrect! include all components of a Pareto chart to receive credit) using the following grading scale:

            A = 90 - 100

            B = 80 – 89

            C = 70 – 79

            D = 60 – 69

            F = 0 – 59

2. Calculate the Mean, Median, Mode, and Mid-range for the exam scores. I am sure that Ms. Gibbs understands the concept of “mean”, but you must to explain “mode” and “mid-range” to her in this report (failure to include explanations of mode and mid-range will result in a loss credit).

3a. Are the data positively skewed, symmetric, or negatively skewed (Yes or No)? Include the use a histogram in your explanation for part 3b.

3b. Include the histogram that you used to answer question 3a. Explain skewness to Ms. Gibbs in this report (failure to do so will result in a points being deducted).

4a. Calculate the Variance and Standard Deviation of the data.

4b. As the test coordinator, interpret each student’s test score - not the class as a group in terms of Standard Deviation. Ms. Gibbs never took statistics in her teacher education program.

5. Construct a boxplot of the test data.

6a. Create a table that lists the z – score for each student’s exam.

6b. As the test coordinator, interpret each students’ test score in terms of the calculated z-score.

7. Assess the data to determine if it is approximately normally distributed (Review the section in the book that discusses how to test for normality). You must include your calculations to support your answer (a graph is not a calculation). If you don’t include your calculations, you will not be given credit. Explain what normally distributed means to Ms. Gibbs.

8. Calculate the 95% Confidence Interval for the exam data. Once you do this, explain your calculated C.I. to Ms. Gibbs.

9. Ms. Gibbs is concerned about Kathleen Drude and John Cho. Since you are the data analyzer for the school, explain their exam performance relative to each other.

This assignment must be submitted on/before the due date. Please use the attached document to submit your responses.

Lab Report-Simple Pendulum- Physics 1401 and 2425 Describe and perform an experiment to investigate the relationship between the length of a simple pendulum -l and its oscillation period- T .

An urn always contains two balls, where each ball is either red or blue.

At each stage a ball is randomly chosen from the urn. A drawn red
ball is always replaced with a blue ball. A drawn blue ball is equally
likely to be replaced by either a red or a blue ball. Suppose that the
urn initially has one red and one blue ball.
(a) Define a Markov chain that should be useful for the above model.
Define its states and give the transition probabilities.
(b) Find the probability that the second ball selected is red.
(c) Find the probability that the third ball selected is red.
(d) Find the long run proportion of time that both balls are red.
(e) Find the long run proportion of drawn balls that are red.

Based on the color of the solutions, determine the direction of the reaction equilibrium shift upon addition of each reagent investigated and write the chemical reaction involving the reagent that is responsible for the shift. Each of the following reagents was added to FeSCN2+ (aq) and the color change is indicated. I'm not sure of the product side of each reaction, please help.

a) Fe(NO3) + FeSCN2+ turned from red to dark red (This one might not have an equation)

b) NH4SCN + FeSCN2+ red turned black

c) SnCl2 + FeSCN2+ red turned cloudy orange

d) AgNO3 + FeSCN2+ red turned cloudy white

e) NaCl + FeSCN2+ red turned orange

f) NaOH + FeSCN2+ red turned dark yellow

g) Na2HPO4 + FeSCN2 red turned clear
