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.
Answer:
yes it is true becasue ya so that equals and that is why 5(4 − x) < 3x + 1
Step-by-step explanation:
Answer:
The answer is $0.69. This is because there are 32 ounces in the bottle, and $22.08/32=0.69, or $0.69.
Step-by-step explanation:
Answer:
29.30
Step-by-step explanation:
Note:
4.5 as a decimal is 0.045
So You can multiply 4.5% by 28 or 0.045 by 28 Either way work.
28 x 4.5%=1.26
28+1.26=29.26
Rounding:
29.30
