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.

<h3>Hello there!</h3><h3>Answer: 1/13</h3>
1/13 would represent the amount of bananas in the basket.
There would be only 1 banana because it would complete he amount of fruits in the basket.
In the basket, we know that there are:
1 orange + 5 apples + 4 kiwis + 2 pears = 12
That would be 12 fruits, but there are suppose to be 13 fruits, which means that the remaining 1 fruit would be a banana.
So, that means that the amount of bananas in the basket is 1 out of 13, or 1/13.

Step-by-step explanation:
Answer:
There are 20 kids total in the class.
Step-by-step explanation:
15/100 × 20 = 3
You can use direct proportion for any percent calculation.
Compare each number with its percent.
3 i
s 15
% of what number? Let the number be x
So, 3 represents 15
% and x represents 100
%
x/
100
= 3/15
Multiply by 100 to isolate x
x = 
x = 20
Check: 15/
100 × 20 = 3
