A survey was conducted that included several questions about how internet users feel about search engines and other websites collecting information about them and using this information either to shape search results or target advertising to them. In one question, participants were asked, "If a search engine kept track of what you search for, and then used that information to personalize your future search results, how would you feel about that?" Respondents could indicate either "Would not be okay with it because you feel it is an invasion of your privacy" or "Would be okay with it, even if it means they are gathering information about you." Frequencies of responses by age group are summarized in the following table. Age Not Okay Okay 18-29 0.1486 0.0603 0.2274 0.0906 30-49 50+ 0.4009 0.0722 (a) What is the probability a survey respondent will say they are not okay with this practice? . (b) Given a respondent is 30-49 years old, what is the probability the respondent will say they are okay with this practice? (Round your answer to four decimal places.) (c) Given a respondent says they are not okay with this practice, what is the probability the respondent is 50+ years old? (Round your answer to four decimal places.) (d) Is the attitude about this practice independent of the age of the respondent? Why or why not? O Yes, because P(okay.1 30-49)=P(30-49 | okay). O Yes, because P(okay n 18-29) 0. . O No, because P(okay | 30-49) P(okay). O No, because these events aren't mutually exclusive. (e) Do attitudes toward this practice for respondents who are 18-29 years old and respondents who are 50+ years old differ?

In the digital age of marketing, special care must be taken to make sure that programmatic ads appearing on websites align with a company's strategy, culture and ethics. For example, in 2017, Nordstrom, Amazon and Whole Foods each faced boycotts from social media users when automated ads for these companies showed up on the Breitbart website (ChiefMarketer.com). It is important for marketing professionals to understand a company's values and culture. The following data are from an experiment designed to investigate the perception of corporate ethical values among individuals specializing in marketing (higher scores indicate higher ethical values). Marketing Managers Marketing Research Advertising 4 6 7 3 6 6 3 5 6 4 5 5 5 5 6 5 6 6 Find the value of the test statistic.   Find the p-value. (Round your answer to three decimal places.) p-value =  (b) At the ? = 0.05 level of significance, we can conclude that there are differences in the perceptions for marketing…

In Exercises 5–8, identify the class width, class midpoints, and class boundaries for the given frequency distribution. Also identify the number of individuals included in the summary. The frequency distributions are based on real data from Appendix B.

A report describes a survey of 251 adult Americans. Participants in the survey were asked how often they disinfect their phone and were asked to respond with one of the following categories: more than once a week, once a week, every other, week, every three weeks, or less often than every three weeks. For this group, 9% responded more than once a week, 52% responded once a week, 26% responded every other week, 6% responded every three weeks, and 7% responded less often than every three weeks. Fill in the table below with the relative frequency distributions. How Often? Relative Frequency More than once a week   Once a week   Every other week   Every three weeks   Less often than every three weeks
