This is a practice exam, not a real exam. What is the independant and dependant variables? I only need the answer to that specific part

The fathers are the same Dutch men from question #1 who were convicted in 1977. The criminal 8:39 PM 8:39 PM record of each of their sons was also compiled. First, compute the unconditional probability of a son's convic- 8:39 PM tion. Second, compute the probability that at least one son was convicted, given that (1) the father was not 16 PM convicted, (2) the father had 1-5 convictions, and (3) the father had six or more convictions. Note that I am 1:19 AM asking you to compute three conditional probabilities. When you have computed these probabilities, discuss 3:12 PM whether father and son convictions are statistically independent. Explain how you can tell. Third, provide 1:19 AM a description of what, in the absence of formal testing, these data seem to reveal about the relationship 15 PM between father and son criminality. 16 PM 52 PM Finally, use the contingency table to determine whether there is a relationship between father and son 1:55 AM conviction. Note that I am asking you to conduct a hypothesis test, so you should show all five steps. Use 1:19 AM a significance level of 0.001. You may use either the definitional or computational formula to compute your 5:31 PM test statistic. What is your conclusion? Discuss what kind of error you potentially made in your decision to M reject or accept the null hypothesis, and what this error means. If and only if you reject the null hypothesis, 8 12:30 PM provide an estimate of the strength of the relationship between father and son conviction. You should 7:26 PM compute all relevant measures of association. Interpret your results. 2:01 PM 2:01 PM Conviction History of Father 2:01 PM Conviction History of Son(s) Not Convicted 1-5 Convictions 6+ Convictions Total 2:01 PM 0 Sons Convicted 465 1234 824 2523 2:01 PM 1+ Sons Convicted 97 665 771 1533 7:56 AM Total 11:16 PM 562 1899 1595 4056 :40 PM 04 PM 1:01 AM 9 9 Premium Account
