Age and Politics Do people’s political philosophy tend to change with age? One technique we may use to answer this question is to see if the mean age of conservatives, moderates, and liberals differ. Go to the book’s website to obtain the data file SullivanStatsSurveyI using the file format of your choice for the version of the text you are using.

(a) State the null and alternative hypotheses.

(b) Verify that the requirements to use the one-way ANOVA procedure are satisfied. Normal probability plots indicate that the sample data come from normal populations.

(c) Are the mean ages for the three political philosophies different at the  level of significance?

(d) Draw boxplots of the ages of the three political philosophies to support the analytic results obtained in part (c).

Employees who are permitted to use their own devices at work create a more efficient and relaxed work environment that can benefit both the company and the employee. This can, however, also cause more harm than good. When employees can access the company’s internet from their own devices, it can open a lot of risks and exposures for them. In the case of “BYOD,” many risks are related to privacy concerns for the employer and the employee. The organization may suffer security risks associated with BYOD, including lost and/or stolen devices, employees leaving the company, viruses, and unsecured wireless networks. Networks and individual computers can both be secured by firewalls. Also, they can automatically intervene when there is an instance of data leak, unauthorized access, or malicious behavior. In either case, an administrator is notified, or the action is blocked.Access by users without restrictions can result in accidental data exposure. Keeping the data on your network secure also means making sure that certain employees cannot access specific types of data. You should allow your IT department to set access levels, create policies that restrict how employees use company data, and require employees to sign a security agreement when they are hired.

• Do you think the benefits of BYOD outweigh the drawbacks?
• How else could the poster mitigate BYOD risks?
