Step-by-step explanation:
Where is the expression?
No mode. There are no two or more of the same price in the given situation.
Answer:
they would divide it
Step-by-step explanation:
because that what some people would do
The numbers are 3 and 12. 12 and 3 have a difference of 9 and 3+12+12=27.
If the mean is 20.8, one standard deviation each way is adding and subtracting 3.1, so 17.7 and 23.9 (68% of values)
Two standard deviations adding and subtracting 3.1*2 = 6.2, or 14.6 and 27.
Three standard deviations is 11.5 and 30.1
So we have
11.5 - 14.6 - 17.7 - 20.8 - 23.9 - 27 - 30.1
Going left to 11.5 is 3 standard deviations out, so 99.7/2 = 49.85%
Going right to 27 is 2 standard deviations out, so 95/2 = 47.5%
Add those two % to get 97.32%
This is hard to do without a picture so I hope that helps!
