Answer: B. The data represent a sample since the data are a subset of units.

Step-by-step explanation:

  • A population is the largest group of entire observations that can be made during a study.
  • A sample is a finite subset of the population that represents the entire population.

Here,

Population = Participants for the study were those who used a popular social networking Web site.

The moment generating function for health care costs experienced by a policyholder is given as follows:
Kaylis [27]

Answer:

0.525 = 52.5%

Step-by-step explanation:

Moment generating function ( Mx(t) ) = ( 4 / 4-t)^3

Reimbursement by Insurer = 70%

<u>Determine the expected reimbursement by insurer for policyholder</u>

 d/dx (Mx(t) ) = d/dt ( 4 / 4-t)^3 = d/dt (1 - t/4 )^-3

                                                 = 3/4 ( 1 - t/4 )^-4 =  3/4

as t → 0

Given that the insurer reimburses 70% = 0.7

expected reimbursement = 0.7 * 3/4  = 0.7 * 0.75 = 0.525
