Where people turn to for news is different for various age groups. Suppose that a study conducted on this issue was based on 200 respondents who were between the ages of 36 and 50 and 200 respondents who were over age 50. Of the 200 respondents who were between the ages of 36 and 50, 77 got their news primarily from newspapers. Of the 200 respondents who were over age 50, 109 got their news primarily from newspapers. Complete parts (a) through (d). a. Given that a respondent is over the age 50, what then is the probability that he or she gets news primarily from newspapers? ___ (round to four decimal places as needed)
b. Given that a respondent gets news primarily from newspapers, what is the probability that he or she is over 50? ___ (round to four decimal places as needed)
c. Explain the difference in the results in (a) and (b).
o The numerator and denominator of the probability is reversed.
o The conditional events are reversed
o There is no difference in the events (a) and (b).
d. Are the two events, whether the respondent is over age 50 and whether he or she gets news primarily from newspapers, independent? Are or are not.
