A stick of proper length I moves past you at speed. There is a time interval between the front end passing you (first event) and the back end passing you (second event). We are interested in this time interval and in the length of the stick, as seen from various frames. (a) Draw snapshots of the two events as seen from your frame, marking with an arrow what is moving (you or the stick) (b) Find the length of the stick as seen from your frame, and the time between the two events, as seen from your frame. (c) Draw snapshots of the two events as seen from the frame of the stick,marking with an arrow what is moving, as seen from this frame (d) Find the length of the stick and the time between the two events, as seen from the frame of the stick. (e) In which frame is the time interval the proper time interval: your frame or the sticks frame? Explain why.

Based on historical information, the distribution of the annual return on Flavorite stock depends on market conditions. The expected annual return for (1) a boom market, (2) an up market, (3) a flat market, (4) a down market, and (5) a crash are shown in the center colum as xi's. The historical probability of each market condition is shown in the right colum as pi's. a. What is the expected annual return of Flavorite stock? b. What is the variance of the annual return of Flavorite stock? c. What is the standard deviation of the annual return of Flavorite stock? d. Assume you work for Flavorite, and are offered a deal to purchase company stock at the beginning of the year. For a fixed fee of 1%, the company will double your annual return on company stock. Using the rules for scaling and translation distributions, what is the expected return on this stock deal? What is the standard deviation of the return on this stock deal? xi pi 1 Boom Market 21% 0.12…

When computer generates random digits, the probability that any particular digit in the set {0,1,2,... 9}is generated on any individual trial is 1/10 0.1. Suppose that we are generating digits one at a time and let X the number of digits that the computer generates to get the first zero. (a) Detemine the probability that the first 0 occurs on the fifth random digit generated_ (6) How many random digits would you expect to have to generate in order to observe the first 0? (c) Calculate and interpret the standard deviation of X.
Suppose 40 participants complete an experiment whero ads are presented subliminally during a task) ads are at very fast rates during movie ads)Participants are then given a recognition test of images of the ads, where two images are presented and participants must choose which of the two was presented earlierBoth men and women (20 of each gender) participate in the study and the researcher predicts that the recognition accuracy will offer across gender. The difference between the sample means in this study was 5%. The for the men was 350 and the the women was 250. What is your t value? A) 3 B) 4.69 C) 3.54 D) 4
