Answer to Problem 1CQQ

The null Hypothesis, H0:p0=p1=p2=p3=p4=p5=p6=p7=p8=p9=110_

The alternative hypothesis, H1 is at least one of the proportions is not equal to the given claim.

Explanation of Solution

Given info:

The dataset shows the heights in cm of 300 randomly chosen subjects. Assume to test the claim that thedata is taken from a population having the last digits which are equally likely to occur at 5% level of significance.

Justification:

Since, there are digits from 0 to 9, there are 10 digits. The claim is to test whether the last digit are equally likely to occur. Each of the digits has equal chance to occur as last digit. Thus, the probability for each digit to occur as last digit has equal probability which is 110 .

Hence, the null hypothesis is,

H0:p0=p1=p2=p3=p4=p5=p6=p7=p8=p9=110_

If the claim is false, then at least one of the digits is different from the given probability of occurrence 110 . Hence, the alternative hypothesis is,

H1: At least one of the proportions is not equal to the given claim.

The class will include a data exercise where students will be introduced to publicly available data sources. Students will gain experience in manipulating data from the web and applying it to understanding the economic and demographic conditions of regions in the U.S. Regions and topics of focus will be determined (by the student with instructor approval) prior to April. What data exercise can I do to fulfill this requirement? Please explain.
Consider the ceocomp dataset of compensation information for the CEO’s of 100 U.S. companies. We wish to fit aregression model to assess the relationship between CEO compensation in thousands of dollars (includes salary andbonus, but not stock gains) and the following variates:AGE: The CEOs age, in yearsEDUCATN: The CEO’s education level (1 = no college degree; 2 = college/undergrad. degree; 3 = grad. degree)BACKGRD: Background type(1= banking/financial; 2 = sales/marketing; 3 = technical; 4 = legal; 5 = other)TENURE: Number of years employed by the firmEXPER: Number of years as the firm CEOSALES: Sales revenues, in millions of dollarsVAL: Market value of the CEO's stock, in natural logarithm unitsPCNTOWN: Percentage of firm's market value owned by the CEOPROF: Profits of the firm, before taxes, in millions of dollars1) Create a scatterplot matrix for this dataset.

6 (Model Selection, Estimation and Prediction of GARCH) Consider the daily returns rt of General Electric Company stock (ticker: "GE") from "2021-01-01" to "2024-03-31", comprising a total of 813 daily returns. Using the "fGarch" package of R, outputs of fitting three GARCH models to the returns are given at the end of this question. Model 1 ARCH (1) with standard normal innovations; Model 2 Model 3 GARCH (1, 1) with Student-t innovations; GARCH (2, 2) with Student-t innovations; Based on the outputs, answer the following questions. (a) What can be inferred from the Standardized Residual Tests conducted on Model 1? (b) Which model do you recommend for prediction between Model 2 and Model 3? Why? (c) Write down the fitted model for the model that you recommended in Part (b). (d) Using the model recommended in Part (b), predict the conditional volatility in the next trading day, specifically trading day 814.
