Explanation:

Step1: Understand box - and - whisker plot properties

In a box - and - whisker plot, the box represents the inter - quartile range (IQR). The left edge of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), and the right edge of the box is the third quartile ($Q_3$). The whiskers extend to the minimum and maximum values. Here, we assume the box - and - whisker plot has $Q_1 = 12$, $Q_2$ (median) between 14 and 18, and $Q_3$ around 18.

Step2: Recall the percentage of data in quartiles

The first quartile ($Q_1$) represents the 25th percentile, the median ($Q_2$) represents the 50th percentile, and the third quartile ($Q_3$) represents the 75th percentile. The data value of 12 is at the first quartile.

Step3: Calculate the percentage of data 12 or more

Since 12 is the first quartile, 75% of the data is 12 or more. Mathematically, we know that the total percentage of data is 100%. The percentage of data less than 12 is 25% (the first quartile). So, the percentage of data 12 or more is $100 - 25=75\%$.

Answer:

75
