State v. Stewart

Did she shoot him dead in self-defense?

What was the ruling in Maryland v. King? What are your thoughts about this ruling?

Department of Homeland Security v. Regents of the University of California summarized in 2 paragraphs

Researchers created two test sheets, each sheet showing 20 photos of the faces of dog‑owner pairs. The two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet the dogs were matched with their owners, while on the second sheet the dogs and owners were deliberately mismatched. Three experiments were conducted, and in all experiments, subjects were asked to "choose the set of dog‑owner pairs that resemble each other, Sheet 11 or Sheet 22 ," and were simply told the aim of the research was a "survey on dog‑owner relationships." In the first experiment, the original sheets were shown to subjects; in the second experiment, just the mouth region of the owners was blacked out in all the pictures on both sheets; while in the third experiment, just the "eye region" of the owners was blacked out. Subjects were assigned at random to the three experimental groups, and in each experiment, the number of subjects who selected the sheet with the dogs and their owners correctly matched was recorded. Experimenters were interested in whether blacking out portions of the faced reduced the ability of subjects to correctly match dogs and owners. The results are displayed.

(a) Is there evidence that blacking out the mouth reduces a subject's ability to choose the sheet which correctly matches the dogs and their owners?

Use the four‑step process to answer the question.

STATE: Which choice best describes the statement of this experiment/study.

1)We want to know if blacking out the mouth region reduces a subject's ability to correctly match the dog‑owner pairs.

2)This is an experiment, since it includes two independent samples.

3)This is an experiment, since the samples are taken randomly.

4)This is an observational study, since the variable of interest is measured but there is no attempt to influence the responses.

5)This is an observational study, since it applies to female Hispanic drivers alone.

PLAN: To examine whether the null hypothesis is true we should test the hypotheses:

?0:?1≠?2 versus ??:?1=?2

?0:?1=?2 versus ??:?1<?2

?0:?1=?2versus ??:?1>?2

?0:?1=?2 versus ??:?1≠?2

SOLVE: Assume the samples can be thought of as an SRS. We can conduct a hypothesiss test since there are more than five successes (correctly identified the pairs) and more than five failures in each sample. Calculate ?̂ 1,?̂ 2, and ?̂. (Enter your answers rounded to four decimal places.)

?̂ 1=

?̂ 2=

?̂ =

Compute the z test statistic. (Enter your answer rounded to four decimal places.)

?=

Using the software of your choice, calculate the one–sided P‑value for the null hypothesis. (Enter your answer rounded to three decimal places.)

?=

CONCLUDE: Which conclusion is correct?

1)There is not enough evidence to conclude that blacking out the mouth region reduces a subject's ability to correctly match dog‑owner pairs.

2)There is enough evidence to conclude that blacking out the mouth region reduces a subject's ability to correctly match dog‑owner pairs.

(b) Is there evidence that blacking out the eyes reduces a subject's ability to choose the sheet which correctly matches the dogs and their owners?

STATE: We want to know if blacking out the mouth region reduces a subject's ability to correctly match the dog‑owner pairs.

PLAN: To examine whether the null hypothesis is true we should test the hypotheses:

?0:?1=?2 versus ??:?1<?2

?0:?1=?2 versus ??:?1≠?2

?0:?1≠?2 versus ??:?1=?2

?0:?1=?2versus ??:?1>?2

SOLVE: Assume the samples can be thought of as an simple random sample. We can conduct a hypothesis test since there are more than five successes (correctly identified the pairs) and more than five failures in each sample. Calculate ?̂ 1,?̂ 2, and ?̂ . (Enter your answers for ?̂ 1 and ?̂ rounded to four decimal places, and your answer for ?̂ 2 rounded to one decimal place.)

?̂ 1=

?̂ 2=

?̂ =

Compute the z test statistic. (Enter your answer rounded to one decimal place.)

?=

Using the software of your choice, find the P‑value for the null hypothesis.

0.05<?

0.005<?<0.05

0.0005<?<0.005

?<0.0005

CONCLUDE: Which conclusion is correct?

1)There is strong evidence that blacking out the eye region reduces one's ability to match dog‑owner pairs.

2)There is weak evidence that blacking out the eye region reduces one's ability to match dog‑owner pairs.

(c) Contrast your conclusions in part (a) and (b) in the context of the problem. Select the best choice.

1)The evidence in (a) and (b) are too close to make a conclusion.

2)The conclusions in parts (a) and (b) imply the mouth region plays a larger role in matching dogs than the eye region does.

3)The conclusions in parts (a) and (b) imply the eye region plays a larger role in matching dogs than the mouth region does.

Java OOP - how do I avoid using getter and setter method in player class for better privacy? I am told to use regular method instead. but I dont know how

Thank you

Can you write about the function of the following reagents in the flow cytometry – Annexin V/PI staining:

1. PBS

2. 1X Binding buffer: 10 mM Hepes pH 7.4, 140 mM NaCl and 2.5 mM CaCl2 (10X dilution before use)

3. Annexin V-FITC staining solution

4. Propidium iodine (PI) staining solution

Thank you in advance, I would appreciate it a lot!!!

We are testing the hypothesis of no difference between means of two normally distributed populations (eg number of cracks in bricks). Alternative hypothesis is inequality. Significance is .05. Samples from these populations are X {3,5,6,9] and Y [6,11,15,21]

Sample correlation coefficient p=.993 , V(x) = 6.25 and V(Y) = 40.25

What test is appropriate (explain)?

Calculate appropriate test statistic (two tailed) and the P-Value using table?

State Conclusion

The eight ball, which has a mass of m=0.5kg, is initially moving with a velocity v=4.9i m/s. It the strikes the six ball, which has an identical mass and is initially at rest. After the collision the eight ball is deflected by an angle of theta 27 degrees and the six ball is deflected by an angle psi 31 degrees. (a) Write an expression for the magnitude of six ball's velocity, in terms of the angles given in the eight ball's initial velocity, v.

I would like to power and drive a vehicle using:

2 x 6V geared mini DC motors
1 x 5V Color recognition sensor
1 x Arduino Nano

I this possible? If so please explain how and provide a detailed schematic and list of parts needed. How do I supply 6 V to each motor, if the Arduino Nano only puts out 5 V?

Thanks
