Question 1

The university book shop selects 200 of its more than 8000 customers to participate in a study on service quality in the shop. The book Shop has established a ________ for use in its research.
A)Population
B)Field setting
C)Dependent grouping
D)Sample

Accepted Answer

The correct term is "Sample" because it refers to a subset of individuals from a larger group (the population) chosen to participate in a study, which in this case is the 200 customers selected from the more than 8000 customers of the university book shop.

Question 2

A good sampling frame must be
A)Relevant
B)Complete
C)Precise
D)All of the above

Accepted Answer

A good sampling frame must be relevant, complete, and precise to ensure that it accurately represents the population being studied, includes all members of the population, and clearly identifies who is in the population.

Question 3

How many different sample of size 3 can be taken from the population comprising 5 elements?
A)7
B)12
C)5
D)10

Accepted Answer

The number of different samples of size 3 that can be taken from a population of 5 elements is calculated using the combination formula, which is C(n, k) = n! / [k!(n-k)!], where n is the total number of items, and k is the size of the sample. Here, n=5 and k=3, so C(5, 3) = 5! / [3!(5-3)!] = (5*4*3!) / (3!*2!) = 10.

Question 4

When sample size increases, which of the followings correct?
A)The standard error remains unchanged
B)The standard error increases
C)The standard error declines
D)None of the above

Accepted Answer

The standard error of the mean decreases as the sample size increases because the estimate of the population mean becomes more precise.
