You are given a training data set with two predictor variables: x1 and x2 and 1 numerical response variable y. You are interested in the prediction accuracy of new samples. Suppose you fit a least squares regression model and obtain the statistics shown in the figure below. Based on this given information, what would you do? Choose the correct answer from the following:

Upon fitting a Logistic Regression Classifier on an email data set, we obtained the probability of an email to be a junk (event) or not (non-event) for each of the data samples. Below is a figure that shows the distribution of the emails belonging to these classes in the data set. If the threshold T is set at 0.5, as shown in the above figure, what will the Receiver Operating Characteristic (ROC) curve look like? Select the correct answer from a, b, or c below:

Given a multiple regression model: and the test of the null hypothesis: vs the alternate hypothesis: , if you perform an F test of the null hypothesis and the result is significant at level , then it is not necessary that at least 1 of the t tests of the predictor coefficients will be significant at level . Is the above statement true or false? Choose the correct answer from the following:
