For each of the steps below, explain your work in words, symbols, and pictures.

1. Write the null and alternative hypotheses in words and symbols.

2. Check the conditions necessary to use the Central Limit Theorem.

3. Select an alpha level and use it to find the critical values.

4. Find your test statistic and compare it to the critical values.

5. Compute the p-value of your test statistic and compare it to alpha.

6. Describe what the p-value measures in this hypothesis test.

7. Make a decision about the null hypothesis.

8. Interpret that decision.

What does the term piecewise mean when referring to linear functions? Is a piecewise function always continuous across its entire domain? Explain your answer and give an example. Give an example of a piecewise function using functional notation and state its domain

After the 2016 presidential election, Gallup collected a random sample of 1,021 Americans and estimated that 47% of Americans wanted to keep the electoral college. One month before the election, in October 2016, another random poll of 1,100 Americans estimated that 52% wanted to keep the Electoral College. Statistically speaking, we can look at whether or not we can be sure that there was a change in opinions about keeping the Electoral College between October of 2016 and November of 2016.

(a) What is the point estimate for the November poll?

(b) What is the point estimate for the October poll?

(c) Are these point estimates statistics or parameters? Explain why or why not.

(d) Report and interpret the difference between the two point estimates.

(e) Compute the estimated standard error for the difference between two estimates. Show your work.

(f) Construct and interpret the difference between these groups at the 95% level. Show your work. 1 Now we can also perform a significance test.

(g) State the null hypothesis.

(h) State an alternative hypothesis.

(i) The test statistic z=-2.3012 and its associated p-value is approximately 0.021 for a two-tailed test at the 5% significance level. Interpret this result in regards to the hypotheses you stated above.

Without using the graphics module, write a program to simulate an archery score tracker. Your program should use a Tkinter canvas to draw a target. Your program should allow the user to click the target to mark where their arrow landed on the target (or off).

When the user clicks the target, the program should draw a dot at that location and compute the score. Scores for each ring are as follows: yellow 5, red 4, blue 3, black 2, and white 1. Use Tkinter labels to display the list scores for each arrow, along with the total score. Also, provide a Quit button that closes the window.

Suppose that you have a company that is interested in entering the market for energy drinks. You will be competing with companies such as Rockstar, Red Bull and Monster.

In this exercise, come up with your own marketing campaign that will truly set you apart from the hundreds of energy drink manufacturers. You are free to use real or fictional brand names. You need to present your ad in an 8.5”X 11” paper in Word. You may use any technique available to you (hand-drawn, collage, computer printed, etc.), as long as it fits into the 8.5X11 paper.

Identify three challenges a manager faces in motivating employees today as opposed to 50 years ago. Develop a response that includes examples and evidence to support your ideas, and which clearly communicates the required message to your audience. Organize your response in a clear and logical manner as appropriate for the genre of writing. Use well-structured sentences, audience-appropriate language, and correct conventions of standard American English. Please give good detail.

Using sufficient detail and depth, discuss two take-aways from intrapersonal and interpersonal effectiveness, and how you could use them to improve yourself as a young professional. Concepts from these sections have been listed below for your reference.

Concepts:

• Self-awareness

• Self-disclosure and trust

• Establishing your goals consistent with your values and ethics

• Self-management

• Listening and nonverbal communication

• Communicating effectively

• Persuading individuals and audiences

What is the Ecological View of Perception? Please explain this view briefly, but completely, clearly and accurately. Be sure that, in your explanation, you explain what is meant by an "Affordance."

Explain what is meant by the terms Habituation and Dishabituation, which you learned about in Psychology 101. How are Habituation and Dishabituation used to study perception in infants?

please it is a psychology question

There is an urn containing 9 balls, which can be either green or red. Let X be the number of red balls in the urn, which is unknown. As a prior, assume that all possible values of X from 0 to 9 are equally likely.

(a)  One ball is drawn at random from the urn, and it is red. Compute the Bayes box to give the posterior probability distribution of X. Calculate the posterior mean of X.

(b) Suppose that a second ball is drawn from the urn, without replacing the first, and it is green. Use the posterior distribution of X from part a) as the prior distribution for X and compute the Bayes box and to give the posterior probability distribution of X. Calculate the mean of X.
