   Question

   In an experiment on the effect of food marketing on purchase intentions (Laura Sjardin, Josephine Ruijs, Nora Michon and Lianne van der Poel, 2017), 182 respondents were given a picture on Instagram of a healthy “juice” (fruit juice). The respondents were randomly divided into two groups: half were shown a photo of the juice that had 28 likes; the other half a photo of a juice that had 106,613 likes. Then the respondents had to indicate to what extent to what extent they would intend to buy the juice (“buyinginterest”: a higher score means a higher buying intention). The question was whether the showing a juice with many likes leads to a higher buying intention than a juice with few likes.

   28 likes: 106,613 likes:

    

   Below are the results of an independent t-test.

   

   

   From the results of the analysis, we can see that…

   
   
   1. TRUE: The intention to buy the juice is greater when the juice has many ‘likes’ than when the juice has few ‘likes’; the difference is not significant
   2. FALSE: Intention to buy the juice is greater when the juice has many likes than when the juice has few likes; the difference is significant
   3. FALSE: The intention to buy the juice is lower when the juice has many likes’ than when the juice has few likes; the difference is not significant
   4. FALSE: The intention to buy the juice is less when the juice has many likes’ than when the juice has few likes; the difference is significant
   
   
   1. True
   2. False
   3. False
   4. False
