Water leaks from a vertical cylindrical tank through a small hole in its base at a rate proportional to the square root of the volume of water remaining. The tank initially contains 350 liters and 17 liters leak out during the first day. A. When will the tank be half empty? $t = \text{____}$ days B. How much water will remain in the tank after 3 days? volume = $\text{____}$ Liters

Texts: Two violins are playing the same note A, but one is slightly sharp (higher frequency). You hear the loudness of the combined tone vary with three loud peaks every second. If one violin is tuned to A 440 Hz, what is the frequency of the other?
5. Give a synthesis of 2-bromo-4-fluoroisopropylbenzene starting from isopropylbenzene. ? Br F 6. Below is a variation of the Curtius rearrangement where methanol is used as the solvent instead of water. Using the curved arrow formalism, show all the bond making and bond breaking steps. For clarity, show all important intermediates. The mechanism begins from the point after the azide attack on an acid chloride. $CH_3OH$ heat $OCH_3$

d (5 pts) You are considering the Tukey and Bonferonni adjustments for comparing all pairs of means when $\alpha = 5$. T F: The Tukey procedure will result in fewer Type I errors T F: The Tukey procedure will result in more Type I errors T F: The Bonferonni procedure uses the $\alpha/5$ significance level for each comparison T F: The Tukey procedure controls the familywise error rate T F: The Tukey procedure is more powerful
