# of ways to select 3 defective:: 3C3 = 1

So from Footprint A, what do you have to do, to make Footprint B etc.
Answer:
110,000
Step-by-step explanation:
2 is lower than five so you have to round down
To find the mean, add all of the numbers together and divide by however many numbers there are. You may want to double check, but i got 2,080 for the first question.
To find median it it literally the number in the middle of the list, so for A, the median is 3, B’s median is 1, C is 3, and D is 2.
Range is the difference between the highest and lowest numbers, so you take the highest and subtract the lowest from it. The highest in all of these is 3, and the lowest is 1, so 3-1. The range for all of them is 2.
I hope this is helpful for you :-)
Let me know if any of this doesn’t make sense or if you need more help with it and I’ll comment:)
