Dispenser C is your answer
16/25 x 4/4 = 64/100
64/100 = 0.64, or 64%
Your answer is Dispenser C
hope this helps
You would have to be 30 because multiples of 5 would only be 25 and 30 inbetween those numbers, and 25 is not an even number which it must be if you can say the number counting by 2s
Let m be mean
Mean= sum/ n
Mean= (1720+1687+1367+1614+1460+1867+1436) / 7
m= 11151 / 7
M= 1593
Mean= 1593
Standard deviation
|x-m|^2
For 1st: |1720-1593|^2=8836
For 2nd: |1687-1593|^2=10201
For 3rd: |1367-1593|^2=51076
For 4th: |1614-1593|^2=441
For 5th: |1460-1593|^2=1689
For 6th: |1867-1593|^2=75076
For 7th: |1436-1593|^2=24649
Summation of |x-m|^2 = 171968
Standard deviation sample formula is:
S.D = sqrt((summation of |x-m|^2) / n-1)
S.D=sqrt(171968/6)
S.D=sqrt(28661.33)
S.D=169.30
Standard deviation is 169.30
Answer:
Only one says the mean s higher than the median, so choose that one.
Step-by-step explanation:
Putting them in order gets yout he following list
$99,000
$106,000
$122,000
$124,000
$130,000
$131,000
$114,000
$497,000
$450,000
The average changes if you increase or decrease any of the prices, thought he median does not unless you mess witht he middle value 130,000. Since it mentions the outliers lets look at those. The outliers are the last two because they are more than 3 times the next highest. So, increasing or decreasing these will effet the average in the same way. Also, keep in mind what the median is, and if the verage as is is higher or lower than it., that pretty much answers your question.
