The subjects in the data are college students. In the data, id is student ID, anxiety is student’s anxiety score via Anxiety Scale, selfest is student’s self-esteem score via Rosenberg Self-esteem Scale, GPA is student’s GPA; for gender, 0=female, 1=male; for grade, 1=freshman, 2=junior, 3=senior. We have known that population mean for Anxiety Scale is μ=60 with σ=10. Raise relevant questions ( 2 questions is fine) about the data extensively, the questions can be either about descriptive analysis or inferential...
Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
The data are shown here:

Problem #1: Consider the below matrix A, which you can copy and paste directly into Matlab. The matrix contains 3 columns. The first column consists of Test #1 marks, the second column is Test # 2 marks, and the third column is final exam marks for a large linear algebra course. Each row represents a particular student.A = [36 45 75 81 59 73 77 73 73 65 72 78 65 55 83 73 57 78 84 31 60 83...

The data from data95.dat contains information on 78 seventh-grade students. We want to know how well each of IQ score and self-concept score predicts GPA using least-squares regression. We also want to know which of these explanatory variables predicts GPA better. Give numerical measures that answer these questions. (Round your answers to three decimal places.) (Regressor: IQ) R 2 : (Regressor: Self-Concept) R 2 : Which variable is the better predictor? IQSelf Concept obs gpa iq gender concept 1 7.94...

Notes:
For part i.) Let T= weight of Peterbilt,
V= weight of Volkswagen, F= weight of
Ford
"three" Volkswagen means
sample from V not 3V.
For part iii) Use the following table
Vol<sWasen A shipping company has a large fleet of Peterbilt, T trucks. The distribution of weights in lb of these trucks from Peterbilt, Volkswagen and Ford are N(580, 225), N (100,64) and N(120, 81), respectively, and are independent. i. If one Peterbilt truck, three Volkswagen trucks and...

The revenues from ticket sales are significant, but the sale of food, beverages, and souvenirs has contrib- uted greatly to the overall profitability of the football program. One particular souvenir is the football pro- gram for each game. The number of programs sold at each game is described by the following probabil- ity distribution:...
