As a state employee, professor Hong hasn’t seen a raise since... well, ever.Thus, an important criterion, in fact the most important criterion is to find an exoticregion that can be visited inexpensively. There are three states of nature that could impact costs in these five areas of interest. Professor Hong has determined the average cost per day to visit each region under each of the possible states of nature. This table, which should not be construed as actual vacation advice, appears below. (Remember they are costs. Lower is better. For example, the most optimistic case is the one with lowest cost.)

- Let's assume that there are 500 people in a population. The researcher has access to all 500 participants, and sends a questionnaire that is accessed by a hyperlink. Of the 500 possible subjects, 485 complete it. Does this mean that the results generated from this study will be highly-accurate? What might cause the study to be unreliable?The data file includes the text of three books of the Bible (Joshua, Jonah and Philippians) using the ESV translation. While these are all great books, our only interest for this project is how often each letter is used. Identify those letters whose Cls do not overlap with any the CIs of any of the other letters. (For example the CI [0.042, 0.052] overlaps with [0.050, 0.060] because the upper bound of the first CI is greater than the lower bound of the second CI.) List the letters with the non-overlapping Cis and specify how many such letters there are.The data file includes the text of three books of the Bible (Joshua, Jonah and Philippians) using the ESV translation.

- At a science fair, 4 different groups of students from a local school are showcasing their projects. The groups arrive with their advisors and each group has a different number of students (40, 33, 25, and 50, respectively). A participant is chosen randomly from the entire pool of students. Let’s use the variable X to represent the number of students in the group that the selected participant belongs to. Meanwhile, the event organizers decide to acknowledge the hard work of one of the advisors by ”randomly selecting” one of them for special recognition. Let’s use the variable Y to represent the number of students who came with the chosen advisor. (a) Before doing any computations, which of E(X) or E(Y) do you think is larger? Or are they the same? Why? (b) Compute E(X) and E(Y). Comment.Many cement companies have research and development teams that continuously formulate and experiment different composition of chemicals to fully optimize the cement that they produce. Suppose a research team formulates 5 different mixtures every month. Two mixtures are selected at random from each batch for testing. The possible outcomes of the selection process are represented by pairs. For example, the pair (1, 2) represents the selection of mixtures 1 and 2 for testing. a. List all the different possible outcomes of the selection process. b. Suppose that mixtures 4 and 5 do not meet the requirements of the test. Two mixtures are to be chosen at random. Define ? to be the number of mixtures that does not meet the requirements among those tested. Find the probability distribution of ?. c. Find the cumulative distribution function of ?. Please answer this step by step and justify your answer.How can we classify experimental designs? Explain one in eachcategory.
