Answer questions associated with sampling, variables, hypotheses, errors, significance, standard error, Z tests, and one-sample t tests.

Question 1

A researcher randomly assigns a group of adults to one of two diet plans (Diet Plan A or Diet Plan B). The researcher then measures the amount of weight loss each participant experiences in a two-week period. What are the IV and the DV in this study?

Question 2

A researcher is studying whether the amount of weight loss differs in participants who follow Diet Plan A versus those who follow Diet Plan B. Write the following:

• A directional research hypothesis.
• A nondirectional research hypothesis.
• The null hypothesis.

Question 3

In the general population, it is an established fact that men weigh, on average, more than women. For your study, you randomly sample 100 men and 100 women, recording each participant’s weight, and you find no significant difference in weight based on gender. What type of error is this (Type 1 or Type 2), given that a difference really does exist in the population? Explain your answer.

Question 4

In general, men and women do not differ on IQ. However, as part of your study, you found that women scored significantly higher than men on IQ. Given that you found a difference in your study where none exists in the general population, identify the error (Type 1 or Type 2) and explain your answer.

Question 5

Joan is 72 inches tall. The average (mean) height for adult women is 65 inches, and the standard deviation is 3.5 inches. Complete the following:

• State the null hypothesis.
• State the alternative hypothesis.
• State the percentage of women of which Joan is taller, compared to the population (Hint: think z score and area under the normal curve).
• State whether or not you expect to reject the null hypothesis, given Joan’s height as compared to the population mean. Explain your answer.

Question 6

College students in a large psychology class take a final exam. The mean exam score is 85, and the standard deviation is 5. Using the formula for σ_M , identify the standard error of the mean (σ_M) under the following conditions:

• The sample size is 25.
• The sample size is 16.
• The sample size is 20.

Question 7

As part of a large research study, you administer a new test to 20,000 adults. Before you record or analyze the data, can you assume that the sampling distribution of the mean for this test will be normally distributed? Why or why not?

Question 8

The average (mean) height for adult women is 65 inches, and the standard deviation is 3.5 inches. Given the women you know, you think this number is low, so you record the heights of 25 of your female friends. The average height of your 25 friends is 66.84 inches. If your friends are just a representative sample of adult females, what is the probability that your friends are so tall?

Portion of the Normal Curve Table

z	Area	z	Area	z	Area	z	Area
1.92	.9726	2.27	.9884	2.62	.9956	2.97	.9985
1.93	.9732	2.28	.9887	2.63	.9957	2.98	.9986
1.94	.9738	2.29	.9890	2.64	.9959	2.99	.9986

Question 9

The average (mean) height for adult women is 65 inches, and the standard deviation is 3.5 inches. Given the women you know, you think this number is low, so you record the heights of 9 of your female friends. Below are their heights in inches:

65, 67, 62, 67, 59, 68, 69, 70, 67.

Complete the following:

1. State the nondirectional hypothesis.
2. State the critical t for α = .05 (two tails).
3. Calculate t. Show your work.
4. Answer if the height of your nine friends is significantly different than the population mean. Explain.

Remember, you must show all your work to receive credit.

Submission Requirements

• Submit all answers in one Word document (do not submit multiple files).
• Show your work for questions that require calculations.
• Ensure your answer to each problem is clearly visible (you may want to highlight your answer or use a different font color to set it apart).

Like many established companies, Groupon is facing future challenges that may very well jeopardize their competitive advantage in the marketplace. Taking into consideration changes in consumer behaviors; how Groupon’s Promise affects the consumer’s perceived risk and cognitive dissonance; the five-stage purchase decision process for a typical Groupon user; and the psychological and sociological influences on the Groupon consumer purchase decision process, you, a member of the corporate marketing team are tasked with developing a formal recommendation on what actions the company should take to address each challenge.

SLO# 1 Civil Liberties v Civil Rights (this assignment should be customized by each instructor to better fit his or her teaching materials and/or emphasis and, to minimize student cheating)

Civil liberties and civil rights are mechanical components that have tremendous influence on the way we live our life. Each category can be applied in different situations, to identify different experiences for each individual. People in the USA are beginning to question whether democracy is worth fighting for as more instances are identified in which human beings find themselves ‘above the law’ (e.g. government officials, bureaucrats and civil servants violate laws that otherwise ‘ordinary citizens’ would quickly be found guilty, and be forced to pay fines and/or be confined and incarcerated). Visit the links below, then respond to the ensuing situations [*do your best to overlook authors’ personal opinions and rather consider the issues identified; also, consider the possibility that these situations maybe taking place in any/all of the 50 states across the USA*].

1. Define Civil Liberties; then define Civil Rights. How are they similar? How do they differ? Which civil sequence has more influence on your life as you know it to be now? Why do you believe this to be so?
2. Where do the courts weigh in? Search the Supreme Court database:

https://www.supremecourt.gov

then identify one case for each situation (i.e. Civil Liberties case; then a Civil Rights case). Which situation would have more influence on the quality of life in the states? Which part of the USA would register a deeper impact of judicial decision(s) reached in the case identified (i.e. in relation to making the most of your life experiences)?
