The five-number summary consists of the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. For the given data: - Minimum = 372 - Maximum = 602 - Median (Q2) = (527+522)/2 = 524.5 (since there are 34 data points, the median is the average of the 17th and 18th values when sorted) - Q1 is the median of the first half (excluding the median if the number of data points is odd). Here, Q1 = 480. - Q3 is the median of the second half. Here, Q3 = 551. Therefore, the five-number summary is $372,480,524.5,551,602$.
