A bond is priced at $8,000 and has a duration of 4. What will the price of the bond be if interest rates increase by 2%? The bond price would fall to $7,360 The bond price would remain at $8,000 The bond price would fall to $7,520 The bond price would rise to $8,320
1. The circle of given radius R is displayed in Fig. 1 just to indicate the geometrical positions of two fixed but unknown point-like charges $q_A$ and $q_B$ along with two observational points denoted 1 and 2. The positions of observational points are specified by angle $\alpha$ such that $\cos \alpha = 3/5$. The known point-like test charge $q$ is situated right at the center of the circle. The work done to move the test charge from its current position to point 1 is measured to be equal to $W_1$. The work done to move the test charge from its current position to point 2 is measured as $W_2$. Based on these measurements, you are asked to actually determine charges $q_A$ and $q_B$. Figure 1: Illustration for problem 1. Figure 2: Illustration for problem 2.

QUESTION 9 Suppose that someone claims that Australians spend less time on social media than Americans do, and so we want to compare the mean amount of time per day that Americans and Australians spend on social media. Suppose also that a sample of 80 Americans and a sample of 100 Australians are taken, that the sample of Americans spend a mean of 2.3 hrs per day on social media with a standard deviation of 0.8 hrs, and that the sample of Australians spend a mean of 1.9 hrs per day on social media with a standard deviation of 0.6 hrs. If we want to test this claim about the mean time spent by Americans per day on social media - or $\mu_{US}$ - and by Australians on social media - or $\mu_{Aus}$ - what would our Hypotheses be in terms of $\mu_{US}$ and $\mu_{Aus}$? $H_0: \mu_{US} = \mu_{Aus}$ and $H_a: \mu_{US} \neq \mu_{Aus}$ $H_0: \mu_{US} \leq \mu_{Aus}; H_a: \mu_{US} > \mu_{Aus}$ $H_0: \mu_{US} = \mu_{Aus}$ and $H_a: \mu_{US} > \mu_{Aus}$ $H_0: \mu_{US} \geq \mu_{Aus}$ and $H_a: \mu_{US} < \mu_{Aus}$ $H_0: \mu_{US} > \mu_{Aus}$ and $H_a: \mu_{US} = \mu_{Aus}$ $H_0: \mu_{US} > \mu_{Aus}; H_a: \mu_{US} < \mu_{Aus}$
