Question

About 30% of babies born with a certain ailment recover fully. A hospital is caring for five babies born with this ailment. The random variable represents the number of babies that recover fully. Decide whether the experiment is a bnomial experiment. If it is identify a success, specify the values of n,p, and q and list the possible values of hte random variable x.

Specigy the value of n. Select the correct choice bellow and fill in any answer boxes in your choice.

A. n=

B. This is not a binomial experiment

Specify the value of p. Select the correct choice below and fill in any answer boxes in your choice

A p=

B. This is not a binomial experiment.

Specify the value of q. Select the correct choice below and fill in any answer boxes in your choice.

A. q=

B. This is not a binomial experiment

Answer 1

This is a binomial experiment.

A) n = 5

A) p = 0.3

A) q = 0.7

Answer 2

a) Yes - the outcome expressed as something that either does or does not happen. It is a dichotomous outcome.

b) Baby recovers fully

c) N=7 - 7 babies are observed

d) p=.80 (although some authors use "q" as the probability of success. Whichever definition you use, make sure "q" is 1-p - success or failure is somewhat subjective. p is the probability that the observed event "of interest" happens.

e) q=.20

f) The possible values of x are the number of babies that can possibly recover. This just asks you to enumerate the sample space.

x can equal 0,1,2,3,4,5,6, or 7.

Answer 3

A) n = 5

B) p =.3

C) q = .7
