Without music 51, 51, 33, 46, 44, 51, 51
Assume a Normal distribution. What can be concluded at the a = 0.10 level of significance? For the study we should use?

We find the distance as follows: √(20 - 8)² + (10 - 5)² = √144 + 25 = √169 = 13. The distance from Tirangletown to The Village Square is C. 13.

Hope this helps!
