Question
(1 point) Are students more likely to use marijuana when their parents used drugs? The following table shows a sample of 415 cases with two variables, "student" and parent", and summarizes the categorical breakdown of the sample. The student either "uses" or "not" where a student is labeled as "uses" if he/she recently used marijuana. The "parents" variables takes the value "used" if at least one of the parents used drugs, including alcohol (a) Presume that from the data set we know the following probability: P(student useslparents-used) 0.609053497942387 Use this probability to help fill in the entire table (round to the nearest number of people Students uses Students not Total Parents usedParents not Total 250 165 415 243 172 (b) Now complete the following probabilities: studentnot parent-not) - d) P( P(parents used student- uses) - P(parents-used)- P(students uses) student not parent - useExplanation / Answer
from above: student uses number =243*0.609053497942387=148
b)
P(student =not|parent= not)= 70/172=0.406976744186047
P(student =not|parent= used)=95/243=0.390946502057613
P(parents =used)=243/415=0.585542168674699
P(student =uses)=250/415=0.602409638554217
