4. [10 pts] Consider a simple linear regression model with an intercept. (a) [2 pts] Why does the point ($\bar{x}$, $\bar{y}$) always lie on the fitted regression line. (b) [8 pts] Prove that $\hat{\beta}_1$ is unbiased for $\beta_1$. Hint: $E(\sum_{i=1}^n W_i) = \sum_{i=1}^n [E(W_i)]$, where $W_1, ..., W_n$ are random variables.
Narrative therapy stresses externalizing questions by asking “Was there ever a time in your life when you did not have this problem and, if so, how was that for you?” This approach tries to help clients see that a presenting problem is separate from their identity as persons. a) Discuss 3 reasons why this externalizing/re-storying process might be effective? b) Discuss three specific populations (age, gender, presenting problem) that you think might benefit from this approach and why. c) Discuss at least two techniques from narrative therapy that might assist with this process and discuss why.

Let's say that you want to estimate the proportion of YouTube videos which take place outside (define "outside" to be if any part of the video takes place outdoors). You take a random sample of 173 YouTube videos and determine that 75 of them take place outside. You'd like to estimate the proportion of all YouTube videos which take place outside, so you decide to create a bootstrap interval from the original sample of 173 videos. Describe how you could use a simulation method (similar to using cards or marbles method) to find one Bootstrap sample and compute its Bootstrap sample proportion.
