Consider the following set of data points: $x$ | $y$ ------- | -------- 0 | 1.0 1 | 2.0 2 | 2.5 3 | 3.0 4 | 5.0 We want to fit a spline with one knot at $x = 2$, using two quadratic segments. Additionally, we require continuity at $x = 2$. 1. Determine the coefficients so that the spline passes exactly through all five data points and is continuous at $x = 2$. 2. Using the fitted spline, compute the predicted values of $y$ at $x = 1.5$ and $x = 3.5$.

4. Suppose you roll two dice, a red one and a blue one. Let X be the number on the red die and let Y be the sum of the numbers on both dice. (a) (4 points) Calculate $p(Y \mid x)$ where $x = 3$. In other words, find the probability for each possible sum given that you know the red die comes up 3. Fill in the table below with the conditional probabilities $p(y \mid 3)$. $y$ 0 1 2 3 4 5 6 7 8 9 10 11 12 $p(y \mid 3)$ (b) (4 points) Compute $E(Y \mid x)$. (c) (2 points) Write down an intuitive way of interpreting $E(Y \mid x)$ that explains why you got the answer you got in part (b).
