Answer:
9 is closest whole number
Answer:
There are 10 dogs in the kennels
Step-by-step explanation:
The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.
Which means, if 
the number of dods and 
is the number of cats, then,
Given that there are 20 cats, so 
Now, from equation (i) we have,
.
Hence, there are 10 dogs in the kennels.
The valid prediction for the mean of the population possible using these samples is C. Yes, the variation of the sample means is small
<h3>What is a sample mean?</h3>
It should be noted that a sample mean is an average of a set of data . Also, the sample mean can be used to calculate the standard deviation, central tendency, and the variance of a data set.
The sample mean can be applied to a variety of uses, including calculating population averages.
Here, the sample variance is a measure of the degree to which the numbers in a list are spread out. Here, the numbers given are close to each other.
If the numbers in a list are all close to the expected values, the variance will be small and if they are far away, the variance will be large.
Therefore, the correct option is C.

MEDIAN:
9 (middle)
MEAN:
(12 + 16 + 10 + 9 + 20 + 11 + 20) / 7 = 14
RANGE:
Highest value: 20
Lowest value: 9
Range: 20 - 9 = 11
INTERQUARTILE RANGE:
First quartile: 16 (It is between 12 and 10)
Third quartile: 11 (It is between 20 and 20)
Interquartile range: 16 - 11 = 5
