Answer:
Option (C): The Rome data center is best described by the mean. The New York data center is best described by the median.
Step-by-step explanation:
1. Rome
Minimum=0
Maximum=16
Median ,
Mean = 8
Standard Deviation(σ)=5.4
As, difference between , Maximum -Mean =Mean - Minimum=8
So, Mean will Worthy description to find the center of Data set, given about Rome.
2. New York
Minimum=1
Maximum=20
Median , Q2 = 5.5
Mean = 7.25
Standard Deviation(σ)=6.1
As, for New york , Mean is not the mid value, that is difference between Mean and Minimum is not same as Maximum and Mean.
As, you can see , the three Quartiles , are very close to each other, it means , other data values are quite apart from each other. So, Mean will not appropriately describe the given data.So, in this case Median will suitable to find the center.
Answer:
17
Step-by-step explanation:
n(Band and Choir only)
= 25 - 11 - 7 - 3 = 4
n(Math and Band only)
= 7
n(Math and Choir only)
= 57 - (25 + 17 + 9)
= 6
Exactly 2:
4 + 7 + 6
= 17
