1. A survey showed that 8% of Internet users age 18 and older report keeping a vlog. Referring to the 18-29 age group as young adults, the survey showed that for vloggers 54% are young adults and for non-vloggers 24% are young adults. a. Develop a joint probability table for these data with two rows (vloggers vs non-vloggers) and two columns (young vs older adults), b. What is the probability that an Internet user is a young adult? c. What is the probability that an Internet user keeps a vlog and is a young adult? d. Suppose that in a follow-up phone survey we contact someone who is 24 years old. What is the probability that this person keeps a vlog?
