A car was driven 6 times to measure the distance and the amount of fuel used. The results are as follows: 1 2 3 4 5 6 Distance (km) 20 25 30 35 28 40 Amount of fuel used (L) 2.14 2.75 2.65 3 2.80 2.479 Construct a scatter plot Is there a linear relationship between distance and the amount of fuel used? If so, How would you describe the relationship? What percentage of the variability in the amount of fuel used can be explained by the variability in the distance? Determining the regression line for distance and amount of fuel used.

Suppose there are four points {(8, 1),(4, 1),(0, 1),(?2, ?1)} in the (x, y)-space, where x is the input variable and y is the label variable. We will attempt to linearly separate these four points. (a) [5 points] Suppose the initialization parameters are ?1 = 1 and ?0 = ?1. Write out the equation of the initial linear separator in terms of x. (b) [5 points] Identify the misclassified point(s) in the set of four points using this initial linear separator. (c) [10 points] We will perform one step of the perceptron algorithm. Choose one of these misclassified points, and write out the new set of parameters after one step of gradient descent in terms of the step function ?. (d) [5 points] In this simple example, we can immediately choose the appropriate learning rate ? such that the perceptron algorithm correctly classifies all the points in one step. Write down such an ?.

In an effort to study trends on social media, a sociologist posts the same item on multiple forms of social media and tracks the reactions of friends/followers. Each item starts with a baseline score of 1,000 and each reaction impacts the score in either a positive or negative way. The items, scores, and graphical representations of one of those scores over 8 weeks is provided below.

An antibiotic loses 35% of its effectiveness in each hour after it has been taken. The doctor prescribed a 400mg dose; the first dose was taken at 8am. Construct a model to represent the amount of antibiotic remaining after any given number of hours, then use your model to determine the amount of antibiotic that remains at 1:00pm. Round your answer to the nearest tenth of a milligram.
