Explanation / Answer
Ans:
Is the experiment a binomial experiment?
Yes,this is binomial experiment as there are only two outcomes either baby recover or does not recover.
What is a success in this experiment?
Baby recovers
Specify the value of n. Select the correct choice below and fill in any answer boxes in your choice.
A. n =7
Specify the value of p. Select the correct choice below and fill in any answer boxes in your choice.
A. p =0.2
Specify the value of q. Select the correct choice below and fill in any answer boxes in your choice.
A. q=1-p=1-0.2=0.8
p=probability of success i.e. baby recovers=0.2
q=probability of failure=1-p=1-0.2=0.8
q=0.8
List the possible values of the random variable x.
x equals x=0,1, 2,..., 7
