If the sample regression equation is ŷ = 15 + 5x, which of the following is the correct interpretation of the estimated intercept? Multiple choice question. For every unit increase in x, ŷ increases, on average, by 5 units. The line crosses the x axis at x = 15. The line crosses the y axis at y = 5. The line crosses the y axis at y = 15.

2. We will show that $\sin(2x) = 2\sin(x)$ is NOT an identity. (a) Plot the function $f(x) = \sin(2x) - 2\sin(x)$ on the domain $[0, 2\pi]$, noting that it is NOT always zero! (b) Find the values of $x$ for which $\sin(2x) = 2\sin(x)$. (Note: solve command will only return solutions inside the interval $[0, 2\pi]$, which is okay for this lab.)

Q1(6). Parents were asked if sports are equally important for boys and girls. Suppose that the proportion of parents who agree the equal importance in the population is actually 0.65. In a survey, of the 400 parents interviewed, 70% agreed that boys and girls should have equal opportunities to participate in sports. 1(2). Describe the sampling distribution of the sample proportion of parents who agree that boys and girls should have equal opportunities. 2(4). What is the probability of observing a sample proportion as large as or larger than the observed value $\hat{p} = 0.70$?
