Project question 1
Using the data in the file named Chapter 11 Data Set 2, test the research hypothesis at the .05 level of significance that males raise their hands in class more often than females. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two tailed test.

Question A. The below data correspond to an independent-measures t test. 1. Provide a hypothetical research question that is appropriate for an independent- measures t test. 2. Identify the independent and dependent variables of your research design, including the levels of the independent variable. 3. Describe what an alpha level is, and what the alpha level's relationship is to the null hypothesis in the specific context of your research study. 4. Using the following data below, determine whether the data...
ANOVA Homework 1. How is an ANOVA different from a t-test? 2. When and why do you use a post-hoc test? Indicate when you use a Fisher's test vs. a Tukey's HSD. 3. A researcher was interested in examining the decision making processes of people who work different shifts in a factory. They ask the participants from each shift to answer a set of questions regarding how they would deal with potential issues in the factory. Below are the scores...
Using the data in the file named “Dataset 1,” to determine is there was a change in the number of tons of paper used after the implementation of a recycling program in 25 different districts. a. Is this study using dependent or independent samples? b. What is your research hypothesis? c. Using Excel, calculate your test statistic and p-value. Paste the output here. d. What do you conclude? Below is the data set that is mentioned above Before Recycling 20...
Using the following data set, conduct an independent samples t-test. Use a= 0.05 and a two-tailed test. Sample 1: 14, 14, 13, 13, 10, 12, 14, 15, 17 Sample 2: 15, 11, 15, 13, 14, 13, 14, 14, 15 1. hypotheses: null and alternative 2. t-critical value; shade of regions of rejection 3. t-obtain 4. conclusion 5. decide if significant 6. compute for confidence interval is significant
Data
Conduct an independent samples t-test (a.k.a., between-subjects design). Each sample should have at least n=8 individuals. What to turn in: 1. What is your research question? 2. State the null (Ho) and alternative (H1) hypotheses. 3. Conduct the hypothesis test using an alpha level of .05, and state your conclusion (Reject Ho/Fail to Reject Ho) regarding the original hypotheses. 4. Calculate and interpret a measure of effect size (est. Cohen's d or r2) and a 95% confidence interval. Subject...
In a study on attraction, suppose subjects were asked to rate pictures of females and males taken before and after a face-lift. Subjects rated the pictures on a number of variables. The total attractiveness ratings are given below, with higher numbers meaning higher attractiveness. You are asked to test whether face-lifts improve the looks of the subjects. Subject: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Before: 22 24 26 20 23 22...
Statistics for people who (think they) hate statistics 4th Edition Using the data in Chapter 15 Data Set 1 to answer the questions below. Do the analysis manually or using the Data Analysis tools in excel. a. Compute the correlation between motivation and GPA. b. Test for the significance of the correlation coefficient at the .05 level using a two-tailed test. c. The more highly you are motivated, the more you will study- true or false? which did you select...
The following data are from an experiment designed to investigate the perception of corporate ethical values among individuals who are in marketing.

doesn’t need sample data. That’s how the question was intended to
be.
Il. A friends someone has. A tailed test friends so was done to test whether the amount of narcissism is a good predictor of number of sample of 10 participants was used. Assume an alpha level of.05 and a two- of 9. What statistical test should you use to evaluate the hypothesis above? 10. What are the null and alternative hypotheses in words? Null...
1. What are null hypothesis and alternative hypothesis? 2. Inastatisticaltest,wehavethechoiceofatwo-tailedtest,aleft- tailed test, or a right-tailed test. Which hypothesis is the determining factor for choosing the direction of the test? (In other words, how would you decide it) 3. Forthesamesampledataandnullhypothesis,howdoesthe P-value for a two-tailed test compare to that for a one-tailed test? 4. Using P-value method, how would you reject or fail to reject the null hypothesis? (what is the decision criteria?) How does level of significance matter to the hypothesis...
