The question:

A teacher is trying to figure out how fast he can throw a Baseball, but doesn't have a radar gun. He does have the following:

- Baseball

- Soft styrofoam Block ( In which the ball could become embedded into during a collision)

- A level tabletop

- A metre stick

- A balance scale.

The teacher also has determined the coefficient of friction between the block and table.

NOTE: The kinetic coefficient of friction is determined while sliding.

The task:

Answer the following below questions:

1. Draw a diagram based on the above question.

2. With the aide of diagrams, derive a single equation that the teacher could use to determine the speed of the ball immediately prior to colliding with the block. Show your steps

3. State and explain 3 to 4 assumptions that need to be made such that your equation above is valid.

Describe a scenario where a researcher could use a Goodness of Fit Test to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use? (3 points)

Describe a scenario where a researcher could use a Test for Independence to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use? (3 points)

The Goodness of Fit Test and Test for Independence both use the same formula to calculate chi-square. Why? I.e., explain the logic of the test. (3 points)

Compare the Goodness of Fit Test and the Test for Independence in terms of the number of variables and levels of those that can be compared. In what ways are they similar or different? (3 points)

Describe how the Test for Independence and correlation are similar yet different. (3 points)

A: Assume that the mass of a person is 70kG and 8% of the body mass is blood. If the density of blood is 1.055g/mL, what is the blood volume?

B: Assume that the hematocrit (the ratio of the volume of red blood cells to the total volume of blood) ratio is 0.45, what is the plasma volume of this person?

C: Assume that the average life span of the red blood cell is 120 days. What volume of red blood cells is being destroyed each day? This corresponds to what volume of whole blood?

D: Assume that the hemoglobin concentration in the whole blood is 16g%. How much hemoglobin is degraded each day?

E: The molecular weight of hemoglobin is 66.6kg/mol and each hemoglobin binds four Fe atoms. How much iron is liberated from hemoglobin each day? Give the answer in mg/day and mol/day.

please answer it as soon as Possible. This Q worth a lot of point, Please don't answer it if you are not sure
I expect a long calculation.
Thank You

1) Recently, has the Fed chosen to pursue expansionary monetary policy or is it implementing contractionary policy? Why is this the case and what does it tell you about how the Fed views the current state of the economy?

2) Suppose it is 2014 and the board of governors believes we are about to enter into another recession. Based on where the Federal Funds rate already was at that time, what problem might the FOMC encounter when they attempt to stimulate the economy by purchasing t-bills?

Two types of medication for hives are being tested to determine if there is a difference in the proportions of adult patient reactions. Twenty out of a random sample of 200 adults given medication A still had hives 30 minutes after taking the medication. Twelve out of another random sample of 180 adults given medication B still had hives 30 minutes after taking the medication. Test at a 1% level of significance.

1) For this hypothesis test, the null and alternative hypotheses would be:

2)State the null hypothesis as a complete sentence:

3)State the alternative hypothesis as a complete sentence:

4)State the null and alternative hypothesis as a difference statement

5)This test would require a  _________ test.

6)How could you rewrite the claim to be a left-tail test?

7)Determine the point estimator of drug A

8)Determine the point estimator of drug B

9)Determine the test statistic

10)Determine the p-value

11)Determine the significance level as a decimal number.

12)What would be your formal conclusion?

13)What practical conclusion can we make about the claim? (In a complete sentence)

The class is Psychology - 223 but it's more a Statistics question...

1.I need to describe the hypothesis associated with my research scenario.

2. I need to state my understanding of what each hypotheses mean.

3. I need to identify the null and alternative hypothesis using appropriate statistical symbols and language based on what is being compared in my research scenario.

And can someone please explain to me how to use that immage up load thing that is asking for a URL on the (immage properties), I have no idea what to put in that spot.

PSY 223 Milestone Three Worksheet

Review the critical elements that must be addressed in the final project. Use this worksheet to create Milestone Three. A hypothesis is a position about research outcomes. In this assignment, you will describe two hypotheses associated with your research scenario.

Points to consider: A researcher acts like the coach of a sports team. In a pregame meeting, a coach describes the possible scenarios associated with outcomes of a game. “If we win, it means we go to the playoffs; if we lose it means our season is over.” The coach’s specificity helps ensure everyone is clear on what the team is up against and what is at stake. Before doing an analysis, researchers do something similar. They acknowledge potential outcomes of the upcoming analysis. “We can find either: (a) variation in the data reflects chance, or (b) variation in the data is due to a systematic law.” Researchers call position (a) null hypothesis (symbolized H₀). Researchers call position (b) alternative hypothesis (symbolized H_a). A researcher customizes the hypotheses to a study, using symbols and information about the specific study.

1. Indicate your research hypotheses (null and alternative), incorporating the appropriate symbols. [To answer this question, you need, in part, to look at the research scenario.]  

2.State what the hypotheses mean.

[Some overlap may exist with your answer to # 1. These are related rather than mutually exclusive questions.]

Scenario 2 (Forensic Psychology)

Levels of groups' certainties about their eyewitness testimony to a simulated crime were compared. The first group was set up to be "right" in its eyewitness accounts and the second group was set up to be "wrong"; the desire was to see if confidence differed across groups. Thirty-four participants were recruited from a college campus and randomly divided into two groups, both of which were shown a video of a crime scenario (length: 58 seconds) in which the perpetrator's facial characteristics (with respect to the camera) were clearly visible at two separate points and sporadically visible at others. Half the participants then were shown a five-individual lineup that contained the perpetrator in the video ("Group A"), and half the participants were shown a five-individual lineup that did not contain the perpetrator ("Group B"). Participants were asked to (a) identify if and where the perpetrator was in the lineup and (b) provide a rating of confidence on a scale from 1 to 10 (10 being highly confident) that the selection was the same as the person seen in the video committing the crime. All participants signed consent forms, were told they could leave the study at any time, and were told they would be debriefed. Data on the confidence ratings are shown below (also found in the Data Set Scenario 2 Excel file).
