. Give the confidence interval for the regression coefficient B4 by considering the following. 40 observations in the sample 90% confidence level . • • 4 predictor variables Use the same information in Question 3 to state the hypothesis test, test statistic and decision rule. Write the following regression function in the appropriate matrices if the sample size is 3. Y₁ = Bo + B₁X₁1+ B₂X12 + 81. Why would we want to obtain a correlation matrix? Explain what 734 means. How would interpret a value of 0.75 for 734? The following data set is obtained. Sixty beetles were researched and the following variables were observed and measured. X₁ legsize in milimeter X₂ bodylength in grams = X3 = weight X4 age in months Study the correlation matrix and then formulate a question that can be answered by a regression model. That is, identify a response (dependent variable). X1 X2 X3 X4 X1 1 X2 0.2 1 X3 0.9 0.85 1 X4 0.1 0.13 0.89 1
