MATH 143M SJSU Corresponding Dominant Eigen Value of Matrix MATLAB Coding Task
This project computes the two largest eigenvalues of a 50x50 matrix. You will use the usual Power Method to compute the largest eigenvalue. For the next largest eigenvalue, you can use an “Annihilation or Deflation or Shifting technique” discussed in class and also in our book. The matrix A is tridiagonal. Its main diagonal has ones on it. The super diagonal (the diagonal above the main diagonal) has negative-ones on it. The sub-diagonal (below the main diagonal) has negative-ones also. Our starting vector xo has all ones. Our tolerance is 0.01.Turn in the following on one page1) Draw Gershgorin Circles that contain the eigenvalues of A. Use “insert” from the menu to locate and draw circles.
2) Based on part (1), what is the spectral radius of A. Print your answer here: _______________3) With a starting vector xo= [1 1 1 1….1]T, apply the usual power method to estimate lmax , the dominant- eigenvalue of matrix A. Use a tolerance of 0.01. Print your answer with 4 decimals: ____________4) Print the number of iterations required to converge. ____________5) Use the deflation technique discussed in class to compute the second largest eigenvalue. Tolerance = 0.01 Print the second largest eigenvalue with 4 decimals: _________________6) Print the number of iterations required to converge. ___________7) Print your computer program here. As discussed in class, the main body of your program is 3 lines, so your program should not be long.

Grand Canyon University Statistics MANOVA Project
A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an on-line website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video made by the same nurse practitioner. The researcher looked at three different ratings of the presentation: difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in whether the interactive website is superior because that is the most cost-effective way of delivering the information. ***Please find the complete assignment attached with the values given for this project.****

MTH 245 George Mason High School Exploratory Data Analysis Project
Purpose:
This project is to help you apply concepts to real world, real data analysis. In the real-world computers do most of the hard work for statisticians. This project will help you understand how an informative decision is made using data analysis. After completing this project, you should be able to determine which statistical procedures are appropriate; use StatCrunch 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 list contains the data for different Qualitative and Quantitative variable. Your project is to obtain the results based on the following questions using StatCrunch. Copy the StatCrunch results (graph plus answer) into summary document using the guidelines in section C.
Directions:
Do all of the work below with the Database of MATH ACT SCORES Download MATH ACT SCORES
Data: The Data set is on the project page on canvas(MATH ACT SCORES). Use StatCrunch to obtain results for the following questions.
A) Exploratory Data Analysis
Obtain the mean and standard deviation for ACT Math scores for each class level (freshmen, sophomores, juniors, seniors) and interpret the results
Obtain the five number summary of ACT Math score for each class levels. Do any of these class levels have outliers?
Construct a boxplot and use it to investigate the data for outliers
Construct a histogram, and normal probability plot (QQ Plot) for ACT Math score for each class level.
B) Inferential Statistics
Construct and interpret a 95% confidence interval for µ, for the mean ACT Math score for each class level.
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.
o Interpret the mean, and standard deviation in context of the data given.
o Compare the measures of center and comment on which measure of center would best describe the data given.
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. Identify which class level has an outlier
o Comment on your assessment of normality.
o Which test will be most appropriate for the inferential statistics (confidence Interval)? Z-test or t-test? Why?
o Write an interpretation for the confidence interval estimate in context of the data.
o State the summary, interpretation and conclusion of your Investigation if there is a relationship between Age and performance in ACT Math score of undergraduate student at UVA.; Provide an equation can be used to predict ACT math score based on age; how reliable would the prediction be?
