- Social media provides an enormous amount of data about the activities and habits of people using social platforms like Face book and Twitter. The belief is that mining that data provides a treasure trove for those who seek to quantify and predict future human behavior. A marketer is planning a survey of Internet users in the United States to determine social media usage. The objective of the survey is to gain insight on these three items: key social media platforms used, frequency of social media usage, and demographics of key social media platform users. a. For each of the three items listed, indicate whether the variables are categorical or numerical. If a variable is numerical, is it dis crete or continuous? b. Develop five categorical questions for the survey. c. Develop five numerical questions for the survey.assume that the facility has been operational for 6 months. The company was fully staffed on Day 1 but recently has seen an increase in turnover. In response, the HR Director (located in NE) began the process of gathering data from both turnover reports/exit interviews from both locations for the first half of the year (January – June). Below is a breakdown of turnover by Position, Exit Month, Department, Location, Manager, and Reason. Unfortunately, the Reason has not been recorded consistently at the Texas location and the HR Manager (who would know this information) has recently left the company.

- 2. The scores for 15 persons on the Stressful Life Events Inventory (SLEI) and the scores for 15 other persons on the Major Stressors Questionnaire (MSQ) are presented in the Assessment 3 Data Excel file in the Stress Scores tab. For both surveys, higher scores mean that the person has experienced more stressors recently, suggesting a greater risk for stress-related symptoms such as acute anxiety attacks. Open the Assessment 3 Data Excel file and look over the SLEI and MSQ raw scores and z-scores in the Stress Scores tab. A. Please take a look at Participant 8 and 23 raw scores and z-scores. Who is at the greatest risk for acute anxiety attacks, Participant 8 or 23? Please make sure to briefly explain your answer based on the z- scores. B. What is the probability that someone will score higher than 40 on the SLEI? Is this unusual? Why or why not? What is the probability that someone will score higher than 125 on the MSQ? Is this unusual? Why or why not? (Please make sure to look up…3. Travelers who have no intention of showing up often fail to cancel their hotel reservations in a timely manner. These travelers are known, in the parlance of the hospitality trade, as "no-shows". To protect against no-shows and late cancellations, hotels invariably overbook rooms. A recent study examined the problems of over-booking rooms in the hotel industry. The following data, extracted from the study represent the daily numbers of late cancellations and no-shows for a random sample of 10 days at a hotel: 18, 16, 16, 16, 14, 18, 16, 18, 14, 19. e) Suppose the relative frequency distribution for the data is bell-shaped, then what percentage of observations are more than 18.2?
