2023 Math 1016 Project Phases F23

Project Phase 2: Confidence Interval (15 points) Select one of your quantitative variables (usually the dependent variable). Using StatCrunch run a summary analysis (directions will be given in class) 1) What are the mean and standard deviation of your variable (3 pts) 2) Include the Summary Statistics table from StatCrunch. (2 pts) Using StatCrunch run a confidence interval analysis (directions will be given in class). 3) What is the 95% Confidence Interval of your variable. (3 points) 4) Include the Confidence Interval table from StatCrunch or show your calculations. (2 pts) 5) Describe the meaning of the confidence interval in terms of your variable. (3 pts) 6) What is the margin of error of your variable? (2 pts) Project Phase 3: Hypothesis Test (15 points) 1) Use the same variable that was used for phase 2. Make a claim about the mean – this claim may come from the internet. Later you will test this claim with your data in steps 4 - 8 (1 pt) 2) Write both the null and alternative hypothesis. (2 pts) 3) Which hypothesis is your claim? (1 pt) Using StatCrunch run a hypothesis test (directions will be given in class). 4) What are the values of the test statistic and the p value. (2 pts) 5) Include the Hypothesis Test table from Statcrunch (1 pts) 6) Is your p value less than the alpha value using alpha = .05. (1 pts) 7) Are you going to reject or fail to reject the null hypothesis? (2 pts) 8) Write your final conclusion using a complete sentence in reference to the context of your problem (2 pts) 9) Based on your answer to 7, what type of error is possible? (type 1 or 2) (1 pt) 10) Describe that possible error in term of your variable. (2 pts) Project Phase 4: One Way ANOVA (15 points) 1) State the populations being compared, the null and alternative hypothesis, and the claim. (3 pts) Using StatCrunch run a hypothesis test (directions will be given in class). 2) What are the values of the test statistic (F stat) and the P value. (3 pts) 3) Include the ANOVA table from Statcrunch (3 pts) 4) Is your p value less than the alpha value using alpha = .05. (1 pts) 5) Are you going to reject or fail to reject the null hypothesis? (2 pts) 6) Write your final conclusion using a complete sentence in reference to the context of your problem (3 pts)
