Cigarette Smoking A researcher found that a cigarette smoker smokes on average 30 cigarettes a day. She feels that this average is too low. Stre selected a random sample of 11 smokers and found that the mean number of cigarettes they smoked per day . The sample standard deviation was 2.5 . At =0.05, is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the P-value method and a TI-83 Plus/TI-84 Plus calculator. Part 1 of 4 (a) State the hypotheses and identify the claim. H0:H1:>30 This hypothesis test is a test. Part: 1/4 Part 2 of 4 (b) Find the P-value. Round the answer to at least four decimal places..

Chapter 9 Exercise 15. Write a function my implode that works just like the predefined implode (without using implode). In other words, it should be a function of type char list string that takes a list of characters and returns the string containing those same characters in that same order. Hint: since the function is taking a list, applying an action to each item, and returning a single item that is not a list, using foldl or foldr would be a good idea..

Companies A and B have been offered the following rates. Company A requires a floating-rate loan. Company B requires a fixed rate loan. Design a swap that will appear equally attractive to both parties (split any gains from the swap right down the middle). A diagram of the swap is shown above. What is the value of X (the fixed payment that company B makes to Company A) in the swap you designed? (Enter 11.51% as 0.1151. Required precision: 0.0001 +/- 0.0001).

Company P has commissioned an economic torecast trom consultancy A in order to choose the optimal level of investment in a new project. The profitability of the project depends on the level of investment I and on a random variable (the state of the market). The consultancy can determine the correct value of , and will write a report informing the company, which will then choose I. The company believes that random variable is uniformly distributed on the interval [0,10]. The payoff to the company from investment I in state is P(I)=1000(I)2 The consultancy is paid a fixed amount F regardless of what it reports. However, it has a hidden stake in the outcome of the project; its payoff if the company invests I in state is A(I)=F(I1.05)2 Assume that F is fixed by law (i.e. not chosen by the company or the consultancy) and is small enough that the contract (commission) will always be offered and accepted. a. Will the consultancy report truthfully? Why or why not? [4 marks] b. What would you expect equilibrium to look like? [4 marks] c. Find an equilibrium in which the consultant's report is ignored; what will the company invest? [5 marks] d. Now find an equilibrium in which the company responds to the report by making either a high or a low investment IHigh or ILow. Find these investment levels and the 'trigger level' of the consultant's report above which the company will choose the high level of investment. [10 marks] e. Are there more efficient equilibria (where the consultant's report conveys more useful information - i.e., where the investment level is more sensitive to the report? For extra credit, can you find a formula for an equilibrium with three levels of investment? [10 marks] f. Finally, can you describe an alternative fee structure for the consultant that would lead to an efficient outcome (where the company makes maximum use of the consultant's information)? [5 marks].

CLO 4: Develop the network application using socket programming. To assess the student's Learning Outcome 4, namely, the ability to develop network application using socket programming detailed as: 1. A simple socket server and client 2. A server-client application that functions like a full-fledged socket application, complete with its own custom header and content. 3. Build-in Python or any other programming language is accepted. 4. Written report as per the specification provided. Introduction Generally, the Socket allows the exchange of information between processes on the same machine or across a network, distributing work to the most efficient machine, and easily allowing access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP. Task Description: You are required to create a prototype for a chat application that enables users to communicate directly with one another in order to accomplish the above-mentioned goal. The prototype must provide unrestricted access to the password-protected network for all users and offer a direct channel of communication between any two online users. Any programming language may be used to implement the prototype, but you must utilize sockets; any libraries used to abstract away the networking portion of this network application prototype will not be marked. The client-server and peer-to-peer network applications' fundamental functionalities must be shown in the prototype. Elementary Prerequisites: 1. The prototype will be constructed using a hybrid architecture that adapts to peer-topeer and client-server architectures. The prototype, then, will exhibit off the fundamental components of client-server and peer-to-peer network applications. 2. The prototype will use TCP socket connections; 3. It will include a client and a server; 4. A client must authenticate before connecting to the server. - Users will be able to send and receive text messages straight from any other users using the prototype at any time, as well as check who else is online and available to chat to. Completeness Requirements: 1. Users will be able to send and receive messages simultaneously and can disconnect from conversations at any moment. 2. The receiving end will send an acknowledgement to the sending end to confirm receipt of the message..
