You are analyzing historic unit costs for 18'' Class 5 reinforced concrete pipe is a database. The unit costs include all costs-material, labor, equipment, and other, for the excavation, bedding, pipe and backfill. Refer to the following table:

What is the median unit cost?

A$48.22

B$48.35

C$40.00

D$46.59

Show Suggested Answer

Suggested Answer: C

The median cost is found by ordering the unit costs and selecting the middle value. The ordered costs are:

$26.78, $34.50, $37.30, $40.00, $46.59, $55.00, $55.00, $65.00, $75.00

Since there are nine data points, the fifth value in this list is the median:

C . $40.00 is the median unit cost.

Not sure about $40.00, that feels off.

$46.59 seems way too low for this type of pipe.

I vaguely remember that the median is less affected by extreme values, so maybe $46.59 could be the answer?

I feel like $48.35 seems reasonable based on what we discussed in class about average costs, but I might be second-guessing myself.

I think the median is the middle value, but I can't recall if we need to sort the costs first.

I remember we practiced calculating medians with similar data sets, but I'm not entirely sure how to handle the outliers in this case.

No problem, I've got this. Median is the middle value when the data is sorted, so I just need to put these 18 numbers in order and select the 9th one. Easy peasy.

Ugh, I hate questions like this. Calculating the median is such a pain, and I always get mixed up trying to sort the values. I hope I can figure this out without too much trouble.

Hmm, this looks straightforward enough. I just need to find the middle value in the list of 18 numbers. I'm pretty confident I can handle this one.

Okay, let's see. The question is asking for the median unit cost, and we have a table of 18 different unit costs. To find the median, I'll need to sort the values from lowest to highest and select the middle value.

I'm going with option D. $46.59 seems like a reasonable median based on the information provided. Though I do wonder why the unit costs are in increments of $0.13. Weird, but I'll go with it.

Haha, the person who came up with option C must be a real comedian. $40.00 as the median? That's about as realistic as a unicorn riding a flying saucer.
