Answer:
28 ≤ x ≤40
Step-by-step explanation:
Arrange the data from the smallest to the largest
26, 27, 28,32, 32, 33, 35, 36, 38, 40,42,48
Identify the median value
26, 27, 28,32, 32,<u> 33, 35</u>, 36, 38, 40,42,48
Getting the median
(33+35)/2 = 68/2 = 34 minutes
You want your time to be last year's median time with an absolute deviation of at most 6 minutes
This mean ±6 minutes, hence this will be 34 ± 6
34+6=40 and 34-6=28
The inequality will be 28 ≤ x ≤40
