Problem
Two friends play a card game 12 times. The winning scores are listed. \( 253,266,268,278,281,286,295,302,308,315,327,342 \) Determine the five-number summary of the data. Enter the answer in eacl Minimum: Lower quartile: Median: Upper quartile: Maximum:
Solution
Step 1 ：Sort the data: \( 253,266,268,278,281,286,295,302,308,315,327,342 \)
Step 2 ：Calculate Quartiles: Q1=\( \frac{266+268}{2} = 267 \), Q2=\( \frac{286+295}{2} = 290.5 \), Q3=\( \frac{315+327}{2} = 321 \)
Step 3 ：Five-number summary: Minimum=253, Q1=267, Q2=290.5 (Median), Q3=321, Maximum=342
