- The American Community Survey is limited to the family population and excludes the population living in institutions, college dormitories, and other group accommodations. The composition of Montana families in 2003 is as follows: 1) Given this table, if 1 circular graph and a Pareto diagram were built. (TABLE IN IMG) ¿Which would be more informative and why?In a study conducted by Zogby International for the Democrat and Chronicle, more than 700 New Yorkers were polled to determine whether the New York state government works. Respondents surveyed were asked questions involving pay cuts for state legislators, restrictions on lobbyists, term limits for legislators, and whether state citizens should be able to put matters directly on the state ballot for a vote. The results regarding several proposed reforms had broad support, crossing all demographic and political lines. Suppose that a follow-up survey of 100 individuals who live in the western region of New York was conducted. The party affiliation (Democrat, Independent, Republican) of each individual surveyed was recorded, as well as their responses to the following three questions. Should legislative pay be cut for every day the state budget is late? Yes _________ No _________ Should there be more restrictions on lobbyists? Yes _________ No _________ Should there be term limits…In order to capitalize on the growth in ecommerce and the possibility to reduce operational costs, Sam was hired by a supermarket/pharmacy chain who is interested in offering online and mobile application services.

- ClairLinx Wireless, a start-up cell phone company, has divided its market of potential customers into three major groups: single, working; married, working; and retired. ClairLinx surveyed 500 potential customers and asked each, "Of the following, which do you consider to be the most important feature in a cell phone service plan: free nights and weekends, free long distance and roaming, or free calls to customers with the same company?" Each of the 500 potential customers in the survey was categorized according to the service plan feature she considers most important and the customer group in which she appears. The data are summarized in the contingency table below. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, type of potential customer and choice of service plan feature, are independent. Round the responses to at least two decimal places. Note:…ClairLinx Wireless, a start-up cell phone company, is trying to decide if it should market specific phone service plans to specific groups of customers. ClairLinx divides its market of potential customers into three major groups: single, working; married, working; and retired. ClairLinx surveyed 500 potential customers (chosen at random) and asked each, "Of the following, which do you consider to be the most important feature in a cell phone service plan: free nights and weekends, free long distance and roaming, or free calls to customers with the same company?" So, there are two variables being considered: type of potential customer ("single, working"; "married, working"; or "retired") and choice of service plan feature ("free calls to other customers", "free nights and weekends", or "free long-distance and roaming"). Each of the 500 potential customers in the survey was categorized according to the service plan feature she considers most important and the customer group in which…A Pew Research study conducted in 2017 found that approximately 75% of Americans believe that robots and computers might one day do many of the jobs currently done by people.† Suppose we have the following data collected from nurses, tax auditors, and fast-food workers in which a higher score means the person feels his or her job is more likely to be automated.

- Economist Arthur Laffer suggests that beyond a certain point, high tax rates depress the economy so much that they actually reduce tax revenues. He proposed tax reductions as a means of stimulating the economy and, as a result, increase tax revenues. In the mid 1990’s Time magazine reported that 30% of the US Congress supported a tax cut as a means of stimulating the economy and increasing tax revenues. Suppose at that time 5 members of congress were randomly selected for an interview and asked whether they supported a tax cut to stimulate the economy. 1.2) Find the probability that at least three of the five members of congress who were interviewed were in favour of a tax cut (rounded off to four decimals).A Pew Research study conducted in 2017 found that approximately 75% of Americans believe that robots and computers might one day do many of the jobs currently done by people.† Suppose we have the following data collected from nurses, tax auditors, and fast-food workers in which a higher score means the person feels his or her job is more likely to be automated.

- Due to COVID19, airlines cut services, such as meals and snacks during flights, and started charging for luggage. However, they are still concerned about service. A group of four carriers hired Denny's Marketing Research Inc. to survey passengers regarding their level of satisfaction with a recent flight. The survey included questions on ticketing, boarding, in-flight service, baggage handling, pilot communication, and so forth. Twenty-five questions offered a range of possible answers: excellent, good, fair, or poor. A response of excellent was given a score of 4, good a 3, fair a 2, and poor a 1. These responses were then totaled, so the total score was an indication of the satisfaction with the flight. The greater the score, the higher the level of satisfaction with the service. The highest possible score was 100. Denny randomly selected and surveyed passengers from the four airlines. Below is the sample information. Is there a difference in the mean satisfaction level among the…Assuming the total number of students studying in the top four universities in the Philippines isapproximately 158,000.And the distribution is as follows:University of the Philippines (UP) - 40% of the total numberAteneo de Manila University (ADMU) - 23,700De La Salle University (DLSU) - 25% of the total numberUniversity of Santo Tomas - 20% of the total numberAnd only the following number of students owns a tablet computer:20% of UP students85% of ADMU students90% of DLSU students85% of UST studentsWhat is the total market penetration of tablet computers among the students of the top fouruniversities?What is the total market size of tablet computers in the top four universities?In recent years, many states have enacted tougher voter identification laws requiring a government issued photo ID. Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws. Document your work in the space provided below. Document how you computed the margin of error and the confidence interval in the space provided below. Round all numbers to 4 decimal places. 2)Is it likely that three-fourths of adults approve of these new laws?
