A division of a company has over 200 employees, 48% of which are male. The company is going to randomly select 10 of these employees to attend a conference. Let Z = the number of male employees chosen
Is Z a binomial variable? Why or why not?
Choose 1
Each trial isn't being classified as a success or failure, so Z is not a binomial variable.
B В
There is no fixed number of trials, so Z is not a binomial variable.
The trials are not independent, so Z is not a binomial variable.
This situation satisfies each of the conditions for a binomial variable, so Z has a binomial
distribution
