Suppose a sample of O-rings was obtained and the wall thickness (in inches) of each
was recorded. Use a normal probability plot to assess whether the sample data could
have come from a population that is normally distributed.

Using the correlation coefficient of the normal probability plot, is it reasonable to conclude that the population is
normally distributed? Select the correct choice below and fill in the answer boxes within your choice.
(Round to three decimal places as needed.)
○ A. Yes. The correlation between the expected z-scores and the observed data, , exceeds the critical value,
. Therefore, it is reasonable to conclude that the data come from a normal population.

13. A pharmaceutical company has developed a new drug for
depression. There is a concern, however, that the drug also
raises the blood pressure of its users. A researcher wants to
conduct a test to validate this claim. Would the manager of the
pharmaceutical company be more concerned about a Type I
error or a Type II error? Explain.

- 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?
