The manager of the customer service division of a major consumer electronics company is interested in determining whether the customers who have purchased a media player made by the company over the past 12 months are satisfied with their products. Which of the following questions in the survey will NOT likely induce a measurement error?

A. How many times have you illegally copied copyrighted sporting events?
B. What is your exact annual income?
C. How many times have you failed to set the time on the media player?
D. How many times have you brought the media player back for service?

Option D

Step-by-step explanation:

The objective of the survey is to assess the satisfaction level of the customers.

Out of the options given, option D is the closest to be used as a basis for gauging the satisfaction level of customers. Option A is irrelevant to the subject under discussion, as it is bears no semblance to the topic.

Option B also has this same tendency, and tend to view the satisfaction from the customers annual income, and not from the firm or its products. Using this definitely could give a measurement error.

Option C talks on inability of the user/customer of the media player to set the time. This failure is borne by the user, and not an inherent fault in the media player. As such, using this as a basis could lead to a measurement error.

Option D is the most suited for the survey.

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
