Question 1 Battery lifetime A firm produces batteries that have a lifetime which is normally distributed with a mean of 360 minutes and a standard deviation of 30 minutes. The firm needs to keep an eye on the production process to ensure that everything is working properly and that batteries are not being produced that do not meet the advertised standard. This is done by calculating the mean of the sample. To do this they regularly select a sample of 36 batteries in order to test the process. (a) Describe the sampling distribution of the sample mean lifetime of batteries (b) State a range within which you would expect the middle 80% of the sample means to lie. (c) If the process were working correctly, what is the probability that a sample would produce a mean of less than 350 minutes? (d) Based on your answer to part (c), what would you conclude about the process if the sample produced a mean life of batteries of 350 minutes? (e) What is the probability that two samples in a row would have a mean life time of less than 350 minutes? Question 2 Production Rates A manufacturing company wishes to estimate the number of items that its workforce can produce on average each hour now that they have a new machine. The factory examined the records for a random sample of 8 hours over the past month. The hourly production rates for these 8 hours were: 142 175 162 158 190 154 160 185 (a) Calculate by hand and interpret the 99 percent confidence interval for the average number of items produced per hour. (b) What assumption did you make in order to answer part (a)? Question 3 Customer Satisfaction (a) An insurance company wants to estimate the proportion of people unsatisfied with their new telephone help service. A survey of 200 callers revealed 45 were unsatisfied with the service. Construct by hand a 95% confidence interval for the proportion of unsatisfied customers. (b) If the company wanted to estimate the sample proportion to within 2% of the population proportion, what sample size would be necessary assuming no prior estimate of the proportion is known? Question 4 Production Rates Continued A manufacturing company wishes to find out whether the productivity of its workforce has increased now that they have a new machine. The factory examined the records for a random sample of 8 hours over the past month. The hourly production rates for these 8 hours were: 142 175 162 158 190 154 160 185 Suppose the production rate before the use of the new machine is 150 units per hour. Test at 5% if the new machine has increased workers’ productivity on average using the critical value approach. Question 5 Take the Pepsi Challenge “Take the Pepsi Challenge” was a marketing campaign used recently by the Pepsi-Cola Company. Coca-Cola drinkers participated in a blind taste test where they were asked to taste unmarked cups of Pepsi and Coke and were asked to select their favourite. In a Pepsi commercial, an announcer stated that “more than half the Coke drinkers prefer the taste of Pepsi”. Suppose 150 Coke drinkers took the Pepsi Challenge and 83 preferred the taste of Pepsi. Test this claim at the 5 percent level of significance using the p-value approach.

Professional Issues in IT (ITPRD202A)Assessment 1: Ethics AssignmentTaskRadio Frequency Identification (RFID) Chip TechnologyOverviewThe purpose of this task is to encourage students to explore a variety of ethical theories and apply them to a contemporary ethical issue in an area of social computing.Timelines and ExpectationsPercentage Value of Task: 20% (35 marks) Due: Week 7 – Friday.Learning Outcomes AssessedThe following learning outcomes for ITPRD202A are assessed by completing this assessment: K1, K2, K4, S3, A1 and A2.Assessment DetailsBackgroundRadio-Frequency Identification (RFID) chip technology has been in existence for many years now. RFID chips have been attached to many items to enable the collection of information about the items, and to track the movement of items. RFID technology has been increasingly utilised in providing efficient and effective solutions for product tracking in the supply chain arena (http://rfidarena.com/2013/11/14/benefits-of-implementing-rfid-insupply-chainmanagement.aspx). Other applications of the technology include library management, transportation management for perishable food and pharmaceutical drugs, and anti-theft processes in retail outlets. More recent applications of this technology include the embedding of RFID chips into animals and ultimately into the human body. A tiny chip can perform a variety of tasks in relation to the object the chip is attached to or embedded within, including the storage of key information related to object.In today’s world, it is quite common with animals (e.g. cats and dogs) to be micro-chipped with ownership information. Proponents of utilising this technology in humans argue that there are many benefits to individuals and communities as a whole including providing ready access to health and medical information, the ability to locate missing persons, and the ability to track and monitor the activities of criminals or persons of interest (e.g. sex offenders, terrorism suspects). Opponents of the utilisation of this technology in humans point to security of information and privacy concerns, and the potential for this technology to result in a ‘big brother’ state where the state has the ability to track and control all citizens.RequirementsStudents are required to undertake an ethical analysis of the benefits and issues associated with RFID chip implants in a human context. Students will prepare a business style report of approximately 2000 words which analyses RFID chip implants in humans through the lens of each of the FOUR (4) ethical philosophies presented in lectures, and ONE (1) element selected from the Australian Computer Society’s (ACS) code of ethics.When analysing RFID chip implants, consider ONE (1) of the following ethical dilemmas:• Is the practice of implanting RFID chips into humans appropriate?• How should the practice of RFID chip implants in humans be governed?• Do the benefits of RFID chip implants for individuals, organisations and/or the broader community outweigh security and privacy concerns with RFID chip implants?For assistance in report writing techniques, see: http://unilearning.uow.edu.au/report/4b.htmlA suggested report structure is as follows.• title page• executive summary• table of contents• introduction• ethical analysis of RFID technology o utilitarianism o deontology o social contract o character based o ACS code of ethics• conclusion• references• appendicesThe introduction section should provide context and background on the issue of RFID chips implanted in humans. It should clearly indicate the dilemma being discussed and provide an overview of how you intend to address the problem and proposed solution(s).The body section of the essay should contain an overview of each of the four ethical theories, and the ACS code of ethics. It should include a discussion and proposed solution for the dilemma, from each of the four ethical theoretical viewpoints, and the ACS code of ethics. The discussion should show an analysis and synthesis of research undertaken and your own ideas.Writing should be validated with concepts from other people’s work.SubmissionPlease submit an ELECTRONIC copy only in Microsoft Word or .pdf format via moodle.

Problem People are often overwhelmed by the relentless march of technology. Accessibility of information is changing the way we work, play, and interact with our friends, family and coworkers. In this time, we consider the future and reflect on how the advent of new technologies will affect our daily lives 10 years in the future. Task You have just returned from a trip in a time machine 10 years into the future. Amazing changes have taken place in just a short time. To a large extent, consumer acceptance of technology makes or breaks a new technology. Your mission is to develop a creative marketing strategy to promote the technological changes you observed in the future and accelerate their acceptance. Process Use the Internet to research up-and- coming technologies (www.howstuffworks.com is a good starting point). Prepare a list of innovations that you believe will occur in the next 10 years. Determine how they will be integrated into society and the effect they will have on our culture. Prepare your findings in a paragraph format. Write a marketing strategy paper in your own words detailing how you would promote the technological changes that you envision for the future. Also note some barriers for acceptance the technology may have to overcome, as well as any legal or ethical challenges or questions you see the new technologies posing.
