A technology company begins a series of focus groups to gather data about the prototype of the new smartphone. Before participants began attending the focus groups, they rated how likely they were to buy a new phone, on a scale of 1-10, with 10 being most likely. Then, after they had a chance to interact with the prototype in the focus groups, they again rated their likelihood of buying a new phone. The results for 10 randomly selected participants in the focus group are as follows:

Participant 1 2 3 4 5 6 7 8 9 10

Before 5 5 4 4 3 7 5 4 4 5

After 8 7 4 7 7 8 10 8 3 6

Use the 0.5 level of significance and assume Normality of scores.
