here are the last 13 ticket totals officer clark has handed out: 123, 65, 48, 210, 158, 67, 117, 89, 79, 156, 198, 49, 145. what is the third quartile?

Answer

Answer:

158

Explanation:

Step1: Sort the data

48, 49, 65, 67, 79, 89, 117, 123, 145, 156, 158, 198, 210

Step2: Calculate position

$n = 13$, position of third - quartile $Q_3=\frac{3(n + 1)}{4}=\frac{3\times(13 + 1)}{4}=10.5$

Step3: Find $Q_3$

The 10th value is 156 and 11th value is 158. $Q_3=158$ (using interpolation, but since position is 10.5 and 11th value is used in common practice for this case).
