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:

You are given a training data set consisting of 10 data points with a single predictor variable, x, and a numerical response, y, i.e., 10 () pairs. Upon fitting a simple linear regression model to this data set, you obtain an R2 value of 0.96. You also fit a cubic regression model to this data set. If the true relationship between the predictor variable and the numerical response variable is of the form: (i.e., quadratic), where takes a very small value, which of the following method would cause an overfitting on the training data set? Choose the correct answer from the following:

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:

List all that are correct: A. Probability must be an integer B. Probability can be  zero C. Probability can be more than 1  

Mark all that are correct? A. Probability must be a positive number B. Probability can be more than 1 C. Probability can not be zero

The late 15th to early 17th centuries (some argue beyond) are known as the Age of Discovery. Several European countries were involved.

Name 3 of these countries; for each of these name one of their colonies. 3. Discuss three of the most significant individuals involved in the rise of Protestantism during the Reformation — one each from Germany, Switzerland (Geneva), and England.  What did each believe? How were their beliefs different from one other?
