Short answer

The box-and-whisker plot is made:

Step-by-step solution

Step 1. Given information.

The following data is given:

$255,287,299,224,200,360,231,388,318,364,381$

Step 2. Formula used.

Information/data provided in the question that are used to solve this particular category of solution/solution.

Step 3. Calculation.

The given numbers are arranged in ascending order:

$255,287,299,224,200,360,231,388,318,364,381$

The median is 299.

The lower quartile is 231 and the upper quartile is 364.

The box and whisker plot is made by joining the upper and lower quartile by a box and the extreme highest and lowest values are joined by a line, called the whisker.
