f What is the difference in the proportions of children who

(f) What is the difference in the proportions of children who do not smoke in the \"no R rated\" and \"anything\" cells? Use 3 decimal places.

(g) What is the relative risk between the proportions of children who do not smoke in the \"no R rated\" and \"anything\" groups? Use 3 decimal places.


(h) Which of the following is the correct interpretation of the relative risk you calculated in (g)?

Those children whose parents do not allow them to watch R rated movies are 1.128 times as likely to smoke as children whose parents allow them to watch anything.

Those children whose parents allow them to watch anything are 1.128 times as likely to smoke as children whose parents do not allow them to watch R rated movies.    

Those children whose parents do not allow them to watch R rated movies are 1.128 times as likely not to smoke as children whose parents allow them to watch anything.

Those children whose parents allow them to watch anything are 1.128 times as likely not to smoke as children whose parents do not allow them to watch R rated movies.

Solution

C) p value is 0

f)

difference in the proportions of children who do not smoke in the \"no R rated\" cells and \"Anything\" cells=698/750-4125/5000=0.1057

g)

relative risk between the proportions of children who do not smoke in the \"no R rated\" and \"anything\" group

=(698+4125)/(5000+750)=0.838783

g)

Those children whose parents allow them to watch anything are 1.128 times as likely to smoke as children whose parents do not allow them to watch R rated movies.
