question 8 of 9\nuse the given data to make a box-and-whisker plot.\n8, 9, 5, 15, 12, 25, 4

Explanation:

Step1: Sort the data set

Sorted data: $4, 5, 8, 9, 12, 15, 25$

Step2: Find minimum value

Minimum = $4$

Step3: Find maximum value

Maximum = $25$

Step4: Calculate median (Q2)

Median is the 4th value: $9$

Step5: Calculate Q1 (lower median)

Lower half: $4, 5, 8$; Q1 = $5$

Step6: Calculate Q3 (upper median)

Upper half: $12, 15, 25$; Q3 = $15$

Step7: Match to box plot

Box plot has whiskers at 4 and 25, box edges at 5 and 15, median line at 9.

Answer:

The correct box-and-whisker plot is the first option (topmost plot, with left whisker at 4, left box edge at 5, median line at 9, right box edge at 15, right whisker at 25).
