Answer: 33 seconds
Step-by-step explanation:To find the first quartile, you need to arrange the data in ascending order and then find the median of the lower half of the data.
First, let's arrange the data in ascending order:
13, 23, 26, 31, 32, 34, 50, 52, 54, 62, 71, 89
Since there are 12 data points, the median of the lower half (Q1) will be the average of the 6th and 7th values:
Q1 = (32 + 34) / 2 = 33
So, the first quartile is 33 seconds.
