Answer:
Yes
Step-by-step explanation:
The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.
It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .
Therefore
(standard deviation/ √sample size)²= variance / n
2/ √20
= 2/4.472
=0.44721
The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n
Answer:
5/6
Step-by-step explanation:
Numbers greater than 1 are 2, 3, 4, 5, 6
5 favourable outcomes
6 total outcomes
P = favourable/total
P = 5/6

answer:
6
step-by-step explanation:
- for this you would find the volume and then divide by 1/2
v = l x w x h
v = (1)(2)(3/2)
v = 3
3 ÷ 1/2 = 6
- therefore, it will take 6 half cubes to fill up the container
