According to a recent study, 30% of American adults will not sit on a public toilet seat. You are surprised by this and select your own random sample of 50 American adults and record X = the number of them that will not sit on a public toilet seat. Would it be appropriate to use a normal distribution to model the sampling distribution of X? No, there are at least 10 "successes" expected, but there are not at least 10 "failures" expected so it is not appropriate to use a normal distribution to model the sampling distribution of X. Yes, the sample size is at least 30, so it is appropriate to use a normal distribution to model the sampling distribution of X. Yes, there are at least 10 "successes" expected and 10 "failures" expected so it is appropriate to use a normal distribution to model the sampling distribution of X. No, the sample size is not at least 50, so it is not appropriate to use a normal distribution to model the sampling distribution of X. No, there are not at least 10 "successes" expected, but there are at least 10 "failures" expected so it is not appropriate to use a normal distribution to model the sampling distribution of X.

![According to a recent study, 30% of American adults will not sit on a public toilet seat. You are surprised by this and select your
own random sample of 50 American adults and record X = the number of them that will not sit on a public toilet seat.
Would it be appropriate to use a normal distribution to model the sampling distribution of X?
No, there are at least 10 "successes" expected, but there are not at least 10 "failures" expected so it is not appropriate to
use a normal distribution to model the sampling distribution of X.
Yes, the sample size is at least 30, so it is appropriate to use a normal distribution to model the sampling distribution of
X.
Yes, there are at least 10 "successes" expected and 10 "failures" expected so it is appropriate to use a normal
distribution to model the sampling distribution of X.
No, the sample size is not at least 50, so it is not appropriate to use a normal distribution to model the sampling
distribution of X.
No, there are not at least 10 "successes" expected, but there are at least 10 "failures" expected so it is not appropriate to
use a normal distribution to model the sampling distribution of X.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fec8216c7-9603-414d-880e-1b2c9e8c3a03%2F3025e553-7371-481b-af24-2cf4298577bc%2Fcgsvpvj_processed.png&w=3840&q=75)
