Final answer:
To make a box-and-whisker plot for the given set of values, first find the minimum, maximum, median, and quartiles. Then construct the plot by plotting the minimum, maximum, and median, and drawing lines to create the whiskers.
Explanation:
To make a box-and-whisker plot for the given set of values, it is necessary to first find the minimum, maximum, median, and quartiles. The minimum value in the set is 25, while the maximum value is 60. The median can be found by ordering the values from least to greatest, which gives us: 25, 25, 30, 35, 45, 45, 50, 55, 60, 60. The median is the middle value, so in this case, it is 45.
To find the quartiles, the set of values needs to be divided into four equal parts. Since there are 10 values, the first quartile (Q1) would be the median of the lower half of the values, which is 25. The third quartile (Q3) would be the median of the upper half of the values, which is 55. Now, we can construct the box-and-whisker plot.
The plot consists of a number line and a box with lines extending from its ends. The minimum and maximum values, 25 and 60, respectively, are plotted as endpoints on the number line. The median, 45, is then plotted as a line inside the box. Finally, lines are drawn from the ends of the box to the minimum and maximum values, creating the whiskers.
