Answer:
For this case the population is described as:
All the college students
And the political have a list of 3456 undergraduates at her college for the sampling frame.
The sample would be the 104 students who return the survey.
Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.
Step-by-step explanation:

For this case we can also find the non reponse rate since we know that the total of questionnaires are 250 and she got back just 104 answered
So we have a non response rate of 58.4 %
Answer:
ab = 1
Step-by-step explanation:
A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.
So the reciprocal of x would be x⁻¹ or ¹⁄ₓ
The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.
So we can write this into an equation and solve,
(See image)
Once we solve, we get the equation (ab-1)(a+b) = 0
We are given info that a+b≠0
So for the above equation to be true, ab-1 has to equal 0
For <em>this</em> to be true, the product ab must equal 1
