- Answer the following questions. 5. What is the term for the arrangement that selects r objects from a set of ii objects when the order of the r objects is not important? What is the formula for calculating the number of possible outcomes for this type of arrangement?3. Create a Pareto chart (without using any Excel template) based on the information in thefollowing table. First, create a spreadsheet in Excel using the data in the table. List the mostfrequent customer problems first and then make the Pareto chart. Interpret the data representedby your Pareto chart. Make sure that given the data your resulting chart looks similar to theone in Figure 8-7.In many colleges, educators are changing their approach to instruction from a “teacher/lecture-centeredmodel” to a “student-centered model” where students learn in a laboratory environment in which lectureis deemphasized and students can proceed at a pace suitable to their learning needs. In once schoolwhere this model was being introduced, of the 743 students who enrolled in the traditional lecture model, 364 passed; of the 567 in the student-centered model, 335 passed. Use a 0.05 level ofsignificance to test the claim that student-centered model results in a higher pass rate than the traditionalmodel?

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 study found that among the 2300 college students who drank energy drinks daily 850 of them binge drank alcohol on a monthly basis. In contrast, 240 of the 1387 students who do not drink energy drinks daily binge drank alcohol monthly. Fill in the contingency table and determine the percentage of college students who drink energy drinks daily among those who DO NOT binge on alcohol.

After 6 weeks of instruction, she gives the students a language comprehension test. The following scores are the number of correct answers for each student. Determine whether the two styles of instruction differ in their effectiveness. Imagery: 12, 13, 11, 11, 13, 13, 15, 12, 9, 12 Repetition: 6, 11, 10, 12, 9, 10, 11, 12, 10, 8 Answer the quetions in picture provided using above information. Thank you
