Identify which class level has an outlier o Comment on your assessment of normality. o Comment on the shape of the distribution, which class level appears to be more approximately normal o Are there any outliers in the data? Include results of your investigation for outliers. o Compare the measures of center and comment on which measure of center would best describe the data given. o Interpret the mean, and standard deviation in context of the data given. Using regression analysis (hint, use scatter plot, r, r2), investigate if there is a relationship between Age and performance in ACT Math score provide an equation can be used to predict ACT math score based on age, Write a Summary and Findings of the Project C) Write-up Write a brief introduction of the project. Construct and interpret a 95% confidence interval for ยต, for the mean ACT Math score for each class level. Construct a histogram, and normal probability plot (QQ Plot) for ACT Math score for each class level B) Inferential Statistics 1. Construct a boxplot and use it to investigate the data for outliers 4. Do any of these class levels have outliers? 3. Obtain the five number summary of ACT Math score for each class levels. Obtain the mean and standard deviation for ACT Math scores for each class level (freshmen, sophomores, juniors, seniors) and interpret the results 2. Directions: A) Exploratory Data Analysis 1. Use StatCrunch (in Mylab Statistics) or Excel to obtain results for the following questions. Data: The Data set is on the project page on canvas. Copy the StatCrunch or Excel results (graph plus answer) into summary document using the guidelines in section C. Your project is to obtain the results based on the following questions using StatCrunch or Excel. This list contains the data for different Qualitative and Quantitative variable. After completing this project, you should be able to determine which statistical procedures are appropriate use StatCrunch or Excel to carry out the procedures and interpret the output The Database of UVA (Excel file) students contains information on the undergraduate students at University of Virginia. This project will help you understand how an informative decision is made using data analysis. In the real-world computers do most of the hard work for statisticians. ![]() Transcribed image text: Purpose This project is to help you apply concepts to real world, real data analysis.
