Question
Fifty-eight percent of adult U.S residents have a Facebook account. You randomly select some U.S adults
and ask them whether or not they have a Facebook account.
For each of the following pieces of R code, run them, report the value, and most importantly match them
to the MEANING of this result in context of this problem.
Give answers accurate to 5 decimal places,
1. pgeom(10,0.58) pgeom(5,0.58)-
2. dbinom(7,12,0.42) -
3. qnbinom(0.25,5,0.58) -
Now match the computations created in 1,2,3 above to their corresponding interpretation.
answer from 1
v answer from 2
answer from 3
a. 25% of the time, you'd run into at most THIS MANY people that did not have Facebook before
finding 5 that did have a Facebook account.
b. The probability that the first person you talk to who has a Facebook account is the 7th, 8th,
9th, 10th, or 11th person you've talked to.
c. The probabitity that out of 12 people asked, exactly 7 of them DID NOT have a Facebook
account.
