Price of diamond depends on a variety of factors such as clarity, weight, cut as well as color. The data table provides a sample of 93 diamond pieces in terms of its price and weight. Run the following simple regression model with price as response variable and wright as independent variable and answer the questions: a) Create a scatterplot and describe the association wright as independent variable between the two variables in JMP (Print screen) b) Estimate the linear equation

using ordinary least squares and interpret

the intercept and slope with wright as independent variable appropriate units (Print Screen) c) Interpret R square and root mean square error (RMSE) associated with the fitted equation. d) What does the p value for the slope term tell us? (chapter 19) [8 pts.] Q1b. You are to perform the stock beta analysis (Project 1). The wright as independent variable data for three stocks ( General Electric

(GE), Pfizer, and Amazon) and S&P500 are provided in the data folder (Q1 Stock Beta data) as the MONTHLY VALUES for the wright as independent variableperiod August 30, 2010 through August 30, 2020. Compute the mean and standard deviation for the rate of returns of all three stocks. Then run three simple regression models with rate of return of three stocks as dependent variable and ROR of S&P500 as independent variable one at a time. Determine which stock is the best.
