# The project must be submitted in paragraph form and not just a list of the calculations from your project.

The project must be submitted in paragraph form and not just a list of the calculations from your project. Be sure your paragraphs flow (not just listing the answers to the questions, but complete sentences with transitions) and are written in third person. You are presenting your results to a nonstatistical audience, do not describe the calculations, describe your results. It should include the following:

Paragraph 1:
Brief summary of the article, including the source
Define the population, sample, and statistic for the study
Statement of the two claims in the article that were tested in this project
Null and alternative hypothesis for both tests run for this project (in words)
Summary of sample statistics (mean, standard deviation, median, quartiles, sample size)
Confidence interval, along with interpretation of the confidence interval
Descriiption of hypothesis test (alpha, test statistic, p-value, conclusion, interpretation)
Summary of sample statistics (sample size, successes, proportion)
Confidence interval, along with interpretation of the confidence interval
Descriiption of hypothesis test (alpha, test statistic, p-value, conclusion, interpretation)

Please use the excel spreadsheet. If you are able to complete sheet labeled “Week 6” I can tip \$100.00.

## PSY805 Evaluate Statistical Analyses

This week, you have learned about t-tests and ANOVA and will apply what you have learned in the evaluation of several research scenarios (Hyperlink and the 3 attached files). For this task, you will read each research scenario and answer the questions regarding each one.
Research Scenario 1A researcher is interested in the effects of a new weight loss supplement. Participants in this double-blind study are randomly assigned to either a group that receives the new supplement or a group that receives a placebo. Participants are weighed before starting the program. After 6 weeks of taking either the new supplement or the placebo, participants return to the lab to be weighed.
Provide the appropriate null and alternative hypotheses.
Determine which type of analysis would be appropriate to answer this research question. Be specific and support your answer using the textbook or other course materials.
Name the independent and dependent variables used in the analysis. What are the levels of the independent variable?
Indicate the levels of measurement for each variable.
Describe the Type I error for this study.
Describe the Type II error for this study.
Research Scenario 2A researcher is interested in whether certain memory strategies help people to remember information. This researcher employs students from a local college, and then randomly assigns them to one of three groups—the visualization group, the mnemonic technique group, and the rote repetition group. Participants in each group receive an hour of instruction regarding how to use the particular technique to remember lists of words. After the instruction, all participants are presented with a list of 60 words that they are instructed to remember. The words are presented one-at-a time on a computer screen. After the last word is presented, all participants are instructed to recall as many words as possible by writing them on a blank sheet of paper. All participants are given 10 minutes to recall the words.
Provide the appropriate null and alternative hypotheses.
Indicate which type of analysis would be appropriate to answer this research question. Be specific and support your answer using the textbook or other course materials.
Name the independent and dependent variables used in the analysis. What are the levels of the independent variable?
Indicate the levels of measurement for each variable.
Describe the Type I error for this study.
Describe the Type II error for this study
Research Scenario 3A local manufacturing company is interested in determining whether their employees are as happy with their jobs as other employees. The manufacturing company asked the workers, who volunteered to participate, to rate their happiness at work on a scale from 1 to 10 where 1 was not at all happy and 10 was extremely happy. The manufacturing company found that the mean happiness rating for their employees is 7.3. In the general population of workers in the United States, the mean happiness rating is 6.
Provide the appropriate null and alternative hypotheses.
Determine which type of analysis would be appropriate to answer this research question. Be specific. Please support your answer using the textbook or other course materials.
Name the variables used in the analysis.
What are the levels of measurement for each variable?
Describe the Type I error for this study.
Describe the Type II error for this study

## Statistics Question

Statistics Assignment Help Read about hypothesis testing (2 attached files and 2 hyperlinks), now apply this knowledge by writing a paper that addresses the following:
Provide an example of a hypothesis where a one-tailed hypothesis test would be used.
Provide an example of a hypothesis where a two-tailed hypothesis test would be used.
If a researcher has set alpha at 0.05 for a two-tailed hypothesis test, what is the p-value required to reject the null hypothesis?
A researcher has set alpha at 0.05. When the researcher analyzes the data from the experiment using a software program, she obtains a p-value equal to 0.932. Based on this p-value, should the researcher reject the null hypothesis or fail to reject the null hypothesis? Please explain your answer.
A researcher has set alpha at 0.01. When the researcher analyzes the data from the experiment using a software program, he obtains a p-value equal to 0.04. Based on this p-value, should the researcher reject the null hypothesis or fail to reject the null hypothesis? Please explain your answer.
A researcher is interested in whether music played during an exam will improve exam performance. Students in one class listen to music during an exam and students in another class take the exam in silence. The researcher set alpha at 0.05. Test scores for both classes are compared using a statistical software program. The mean test score for the class that listened to music during the exam is 95, while the mean test score for the class that took the exam in silence is 82. The obtained p-value from the independent groups t-test is 0.02. Be sure to answer the following questions:State the null and alternative hypothesis.
Establish the conclusion of this study based on the p-value and the means provided.
Describe the Type I error for this study.
Describe the Type II error for this study.

## Discussion 5

Imagine
yourself at a fair playing one of the midway games. Pick a game and
calculate the expected value and post your results along with how you
calculated them. For example, you may decide to throw a basketball to
try to win a \$10 bear. You paid \$2.00 for three shots. What is the
