Answer:
Provided that the sample size, n, is sufficiently large (greater than 30), the distribution of sample means selected from a population will have a normal distribution, according to the Central Limit Theorem.
Explanation:
1. As n increases, the sample mean approaches the population mean
(The Law of Large numbers)
2. The standard error of the sample is
σ/√n
where σ = population standard deviation.
As n increases, the standard error decreases, which means that the error
between the sample and population means decreases.
Answer:
7 units
Step-by-step explanation:
Distance between 2 points
=
Thus, distance PQ

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.
Answer:
The ant travels 1,372 inches in 7 minutes.
Step-by-step explanation:
Since 1 minute = 196 inches
1 × 7 = 7
196 × 7 = 1,372
