Answer:
As the sample size increases, the variability decreases.
Step-by-step explanation:
Variability is the measure of actual entries from mean. The less the deviations the less would be the variance.
For a sample of size n, we have by central limit theorem the mean of sample follows a normal distribution for random samples of large size.
X bar will have std deviation as 
where s is the square root of variance of sample
Thus we find the variability denoted by std deviation is inversely proportion of square root of sample size.
Hence as sample size increases, std error decreases.
As the sample size increases, the variability decreases.
The common difference is basically the number at which the pattern increases.
A's common difference: 2
B's common difference: 9
C's common difference: 5
answer: A, C, B
Answer:3.81 centimeters
Step-by-step explanation:All you have to do is to convert inches into centimeters
So 1 inch=2.54cm
Therefore 1.5inches=(1.5/1)×2.54cm
=3.81cm
7(2e-1)-3=6+6e
14e-7-3=6+6e
14e-10=6+6e
+10 +10
14e=16+6e
-6e -6e
8e=16
8e/8=16/8
E=2
Answer:
Find what <u>both fractions</u> are <u>divisible</u> by.
Step-by-step explanation:
Take 
and if needed, use a multiplication tabel to help you figure out what both numbers are divisible by. 5 and 15 are both divisible by 5. Now you can reduce the answer to 
.
Hope this helps!
