Answer:

No association .

Step-by-step 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 .
