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.

- Many research studies have been conducted to examine how different organizations are on implementing knowledge management processes. For example, studies have proved that larger firms have more resources to utilize, and so they have taken more efforts to implement knowledge management processes. The Journal of Business Research (Aug. 2014) published a study discussing the relationship between knowledge management processes and organizational performance. The table below shows the percentage of different size of firms participated in the study. These firms have been classified in terms of number of employees working. Need step-by-step procedure to answer each question. Randomly select one of the participated company from this study. Let x be the number of employees working in the company. Write the probability distribution of this x. What is the probability that the selected company employs more than 50 employees? Find E(x) and σ.

- Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948.
