In one place, Plato speaks of the soul as a "unity". Yet, in another, he says the soul has distinct parts, each of which has a function. For instance, there is: reason, which guides. the ego, which is the reality principle. the id, or the set of unconscious desires present in every soul. the animus, which is the masculine component. the superego, or one's conscience.

We want to conduct a hypothesis test of the claim that the population mean daily profit of a convenience store is more than 544 dollars. So, we record the daily profit for a random sample of days. The sample has a mean of 550 dollars and a standard deviation of 75 dollars. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 20, and it is from a normally distributed population with a known standard deviation of 78. 0 z = 0 0 t = 0 It is unclear which test statistic to use. (b) The sample has size 18, and it is from a population with a distribution about which we know very little. 0 z = 0 0 t = 0 0 z = 0 It is unclear which test statistic to use

13. (6 points) Derive the formula for the surface area of the torus obtained by revolving $x = r \cos(t) + R$ $y = r \sin(t) + R$ $0 \le t \le 2\pi$ around the x-axis. 14. (6 points) The graph of the curve with polar coordinate representation $r = 1 + 2 \cos \theta$ consists of two "loops" beginning and ending at the origin. Find the area of the region between the inner and outer loops.
