Answer

The 50th percentile is 16 minutes.

Solution

Since the service time is uniformly distributed between 11 and 21 minutes, the 50th percentile (or median) is simply the midpoint of these two values. To calculate the midpoint:   (11 + 21) / 2 = 32 / 2 = 16 Thus, the 50th percentile is 16 minutes.

Extra Insights

To find the 50th percentile (also known as the median) of a uniform distribution, you simply average the lower and upper limits of the distribution. In this case, the limits are 11 minutes and 21 minutes. So, the median is (11 + 21) / 2 = 16 minutes. This means that half of the time, the service technician will take less than 16 minutes, and half the time, they'll take more! Uniform distributions are fascinating because they imply that every outcome within the range is equally likely. This is a key point in statistics and is often applied in various fields, like quality control or risk management, where knowing the range of possibilities can help organizations prepare better. So, whether you're scheduling appointments for oil changes or estimating service times, understanding uniform distributions can smooth out the process!
