Answer:
No association .
Explanation:
Given : A scatter plot is made with the data shown below: Number of Waiters at a Restaurant 5 6 7 8 9 10 11 12 13 Customer Service Rating 4 2 10 7 1 2 8 9 5
To find : What type of association will the scatter plot for these data represent between the number of waiters at a restaurant and its customer service rating.
Solution : We have given :
Number of Waiters at a Restaurant = 5 6 7 8 9 10 11 12 13
Customer Service Rating = 4 2 10 7 1 2 8 9 5 .
Here x coordinates are 5 6 7 8 9 10 11 12 13
y coordinates are 4 2 10 7 1 2 8 9 5 .
(5,4) (6,2) (7,10 )(8,7) (9,1)(10,2)(11, 8) (12, 9) (13, 5)
We can see there is no pattern between x and y coordinates .
Therefore, No association .
