tribution iI DownloauPage16. One of the goals of psychology is to make accurate predictions about phenomena in ourworld. First, a research hypothesis is generated based on a particular topic of interest.What is it that you want to investigate? Second, the variables of interest are specifiedand are defined operationally; how do you want to measure the construct? Third,identify the sample- who do you want to measure? Remember, the larger the sample,the better you will be able to generalize your results to the entire population. Finally,imagine collecting data and compare the relationship between the variables using theappropriate statistical test, and base your conclusions on this evidence. Suppose wewant to examine whether male or female college students differ in their alcoholconsumption. Using this example, answer the following questions below.a. State your research hypothesis.b. What is the quasi-independent variable? What is the dependent variable? Whatis your operational definition of alcohol consumption?C. Specify your sample and sample size.d. Let's say you collected data (see the table below.) Based on the data, what canyou conclude about the relationship between gender, school year, and alcoholconsumption? Write up the results of the study using APA formatting andconsider if the data is normal or skewed. Use the best central tendency measureto describe your data.

Assignment #6 For this assignment, you will be using the Tips Dataset file in Excel. The file contains both qualitative and quantitative variables. Choose two qualitative variables. You will be using a hypothesis test to determine if the two variables are associated. 1. Which two variables did you choose? Create a table to summarize the data from the data file. Example below: Example: Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data). Response Male Female Total Not at all 23 25 48 Somewhat 13 22 35 Very Total 26 16 42 62 63 125 2. Which hypothesis test is appropriate for this type of data? Explain. What is your null hypothesis? What is your alternative hypothesis? 3. Conduct the hypothesis test. Include any output from Excel. What is your test statistic? Using alpha = 0.05 determine the results of your hypothesis test. Explain. 4. Interpret your results into a conclusion based on…
Check for accuracy and respond the last questions 2. For this problem, use Chapter 11 Data Set 3. We want to know if urban and rural residents both have the same attitude toward gun control. a. What is the null hypothesis? The null hypothesis concludes that there is no difference in attitudes toward gun control between urban and rural residents. b. What is the research hypothesis? The research hypothesis suggests that there is a difference in attitudes toward gun control between urban and rural residents. c. Will you be conducting a one-tailed or a two-tailed test? Why? In this case I would conduct a two-tailed test because i’m interested in whether there is a difference in attitudes toward gun control between urban and rural residents, regardless of which direction that difference follows. e.- What is the p-value (hint: it is under “sig” in the output table)? The P-value is 0.44. Do you reject the null hypothesis or fail to reject the null? What do you conclude about urban and…
wants to know if it is better for Instructor Pilots to give flight students feedback in the airplane immediately after each maneuver rather than to wait till they are on the ground and debriefing. Six student pilots are selected. Each student receives immediate feedback on half of their flights and receives delayed (after landing) feedback on the other half of their flights. Average scores for the student’s evaluations are listed in the table below. Show work. Student Pilot Score for Immediate Feedback Score for Feedback Received After on the Ground Student Pilot A 4 2 Student Pilot B 3 4 Student Pilot C 5 2 Student Pilot D 3 3 Student Pilot E 5 3 Student Pilot F 5 2 a. Test the hypothesis that the student pilots receive higher evaluations on flights where they received immediate feedback compared to delayed (after landing) feedback. Use α =.05. Use the four steps of hypothesis testing. b. Calculate Omega squared (ώ2)

Aspirin III: Decision and Conclusion Regarding the experiment in the data frame Aspirin from the abd package, the researchers wanted to know whether or not taking aspirin affects one's risk of developing cancer. Recall that they defined their parameters as follows: p1 = the proportion of ALL individuals who would develop cancer, if all of them were to take aspirin like the subjects in the Aspirin group did. p2 = the proportion of ALL individuals who would develop cancer, if all of them were to take a placebo, like the subjects in the placebo group did. They ran the code for a two-sided significance test and got the following results: ## ## ## Inferential Procedures for the Difference of Two Proportions p1-p2:## cancer grouped by treatment ## ## ## Descriptive Results:## ## yes n estimated.prop## Aspirin 1438 19934 0.07214## Placebo 1427 19942 0.07156## ## ## Inferential Results:## ## Estimate of p1-p2: 0.0005805 ## SE(p1.hat - p2.hat): 0.002586 ## ##…

Need to understand how to solve in excel or using megastat. This is practice exam Suppose Bank of America would like to investigate if the credit score and income level of an individual are independent of one another. Bank of America selected a random sample of 400 adults and asked them to report their credit score range and their income range. The following contingency table presents these results. Credit Score Class Less than 650 650–750 More than 750 Income < $50,000 30 24 27 $50,000 ≤ Income < $100,000 42 47 38 $100,000 ≤ Income < $150,000 49 35 26 Income ≥ $150,000 27 29 26 The expected number of individuals with income between $50,000 and $100,000 and a credit score less than 650 is ________.
