The histogram on the left shows the interval (in minutes) between eruptions of the Old Faithful geyser for all 222 recorded eruptions during a particular month. For this population, the median is 75 minutes. We used technology to take 500 SRSs of size 10 from the population. The 500 values of the sample median are displayed in the histogram on the right. The mean of these 500 values is 73.5 . 1. Is the sample median an unbiased estimator of the population median? Justify your answer. 2. Suppose we had taken samples of size 20 instead of size 10 . Would the variability of the sampling distribution of the sample median be larger, smaller, or about the same? Justify your answer. 3. Describe the shape of the sampling distribution of the sample median.

(a) Use Laplace transforms to solve the IVP: $y'' - y = U(t - 3)$, $y(0) = 0$, $y'(0) = 0$. (b) Find the function $f(t)$ whose inverse Laplace transform is given by $F(s) = \frac{s}{9s^2 - \pi^2} + \frac{s}{s^2 - 4s + 5}$. (c) Let $f(t)$ be a continuous function on $[0, \infty)$ and let $F(s)$ denote its Laplace transform. Find the Laplace transform of the function $g(t) = \int_0^t e^r f(r) dr$ in terms of $F(s)$.

Draw the cash flow diagram for this problem. Gina just turned 25 and she is planning to retire at age 55. She plans to make 30 equal annual deposits into a retirement account and then withdraw $35,000 once per year for 30 years, beginning 5 years after the last deposit. The retirement account earns an annual return of 10%. Tip: You don't need to draw every single period. Use breaks and ellipsis to indicate recurring patterns.
