1. Construct a cumulative frequency distribution of
the 20 brain volumes(cm3) listed below.
Use the classes 900-999, 1000-1099, and so on. (6-classes)
1005 963 1035 1027 1281 1272 1051 1079 1034 1070 1173
1079 1067 1104 1347 1439 1029 1100 1204 1160.Also find relative
frequency for each class interval?
2. Use data above in question 1 to build the frequency polygon. Is
the distribution symmetric?

In what follows use any of the following tests/procedures: Regression, multiple regression, confidence intervals, one sided T-test or two sided T-test. All the procedures should be done with 5% P-value or 95% confidence interval.Some answers are approximated, choose the most appropriate answer. Open Brains data. SETUP: Are the IQ’s for male and female subjects different? Given your job is to confirm or disprove this assertion. I. What test/procedure did you perform? (6.66 points) a. One sided T-test b. Two sided...
In what follows use any of the following tests: Regression, multiple regression, one-sided t-test or two-sided t-test. All conclusions should be based on 5% P-value threshold. Choose the best fitting answer. Open Brains data. 13. Task A: Perform two-sided t-test comparing the IQ and brain volume. What is the P-value? a. 2.30863E-19 b. 1.15432E-19 c. 0.001164071 d. 0.790616477 14. Task B: Perform regression where X-axis is the Volume and Y-axis is the IQ. What is the P-value related to the...

Using Doubly Linked List, and Sorting methods: (In Java) (please attach your output with the answer) (Please answer if it is correct and working) (Have been getting many wrong and spam answers lately) Introduction: In this project, we use the same file structure of Artist and Art to extend the concepts of array and linked list and have them applied to sorting. The input files of p1arts.txt and p1artists.txt have been slightly modified. They are named p7arts.txt and p7artists.txt. Assignments:...
Using Merge Sort: (In Java) (Please screenshot or copy your output file in the answer) In this project, we combine the concepts of Recursion and Merge Sorting. Please note that the focus of this project is on Merging and don't forget the following constraint: Programming Steps: 1) Create a class called Art that implements Comparable interface. 2) Read part of the file and use Merge Sort to sort the array of Art and then write them to a file. 3)...
