Do product labels influence customer perceptions? To find out, researchers recruited more than 500 adults and asked them to estimate the number of calories, amount of added sugar, and amount of fat in a variety of food products. Half of the subjects were randomly assigned to evaluate products with the word 鈥淣atural鈥 on the label, while the other half were assigned to evaluate the same products without the 鈥淣atural鈥 label. On average, the products with the 鈥淣atural鈥 label were judged to have significantly fewer calories. Based on this study, is it reasonable to conclude that including the word 鈥淣atural鈥 on the label causes a reduction in estimated calories?

(a) No, because the adults weren鈥檛 randomly selected from the population of all adults.

(b) No, because there wasn鈥檛 a control group for comparison.

(c) No, because association doesn鈥檛 imply causation.

(d) Yes, because the adults were randomly assigned to the treatments.

(e) Yes, because there were a large number of adults involved in the study

Short Answer

Expert verified

The correct option is (a) No, because the adults weren鈥檛 randomly selected from the population of all adults.

Step by step solution

01

Step 1. Introduction

Customer perception is highly influenced or manipulated by the personal experience that a customer had while buying or selling and using a particular product. If the quality, customer service, price, logo, color, discounts, etc. were able to make an excellent impression on the minds of the customers, they would build a good perception of the brand.

Step 2. Explanation for correct option

In this study, researchers want to find out that do the product labels influence customer perception or not. So, they conducted an experiment. Since the experiment does not randomly choose the adults that were selected for the study. Thus, it is not reasonable to conclude that including the word 鈥渘atural鈥 on the label causes a reduction in estimated calories. So, the option (a) is correct option.

Parking on campus The director of student life at a university wants to estimate the proportion of undergraduate students who regularly park a car on campus. Describe how to select a stratified random sample of approximately 100students. Explain your choice of strata and why stratified random sampling might be preferred in this context.

To investigate if standing up while studying affects performance in an algebra class, a teacher assigns half of the 30students in his class to stand up while studying and assigns the other half to not stand up while studying. To determine who receives which treatment, the teacher identifies the two students who did best on the last exam and randomly assigns one to stand and one to not stand. The teacher does the same for the next two highest-scoring students and continues in this manner until each student is assigned a treatment.

Which of the following best describes this plan?

a. This is an observational study.

b. This is an experiment with blocking.

c. This is a completely randomized experiment.

d. This is a stratified random sample.

e. This is a cluster sample.
