Final answer:
The minimum value is 11, the maximum value is 99, the first quartile is 33, the median is 55, and the third quartile is 77.
Step-by-step explanation:
To find the minimum, maximum, and quartiles, we first need to put the values in order from least to greatest:
11, 22, 33, 44, 55, 66, 77, 88, 99
The minimum value is 11 and the maximum value is 99. To find the quartiles, we divide the data into four equal parts. The first quartile (Q1) is the median of the lower half of the data, which is 33. The second quartile or median (Q2) is 55. The third quartile (Q3) is the median of the upper half of the data, which is 77.
