Suppose you are managing 25 employees, and you need to form three teams to work on three different projects.
Assume that all employees will work on exactly one team. Also, each employee has the same qualifications/skills, so any employee can serve on any team.
The number of employees on each project are as follows: 8 on Team A, 2 on Team B, and 15 on Team C.
(a) How many ways can Team A be selected from the available employees?
(b) Then, how many ways can Team B be selected from the remaining available employees?
(c) Then, how many ways can Team C be selected from the remaining available employees?
(d) Then, how many ways can all teams be selected?
(e) What is the probability that three workers randomly selected from all employees will all be from team A?
a) C(25,8)=
b) C(17,2)=
c) C(15,15)=
d) multiply the above results
e) prob = C(8,3)/C(25,3) =
A large company wants to find out what team-building activity its employees prefer. Which of the following samples can give the most valid generalization?(1 point)
Responses
400 randomly chosen employees from the list of all employees
all 624 female employees in the company
a group with one member from each department
all employees who have worked in the company for 5 years or more
c) a group with one member from each department.
Are you absolutely, 100% sure?
I apologize for the mistake. The correct answer is a) 400 randomly chosen employees from the list of all employees. This ensures that the sample is representative of the entire population of employees and reduces the potential for bias.
So...is it A or C?
The most valid generalization can be obtained from option A- 400 randomly chosen employees from the list of all employees.
