(b) answer the questions below. is there a cluster from 7 to 9? yes no is there a gap from 5 to 6? yes no is the data set symmetric? yes no

Answer

Explanation:

Step1: Identify peak of data set

The peak is where there are the most data - points. Counting the dots on the dot - plot, the most dots are at 4 miles.

Step2: Check for cluster from 7 to 9

There are some dots at 7, 8, and 9 miles, so there is a cluster.

Step3: Check for gap from 5 to 6

There are no dots at 5 and 6 miles, so there is a gap.

Step4: Check for symmetry

The data is not evenly distributed on both sides of a central value, so it is not symmetric.

Answer:

(a) 4 (b) Yes Yes No
