to draw a random sample from normal distribution the method useful is
Answers
Answer:
Because our sample size is greater than 30, the Central Limit Theorem tells us that the sampling distribution will approximate a normal distribution. ... Because we know the population standard deviation and the sample size is large, we'll use the normal distribution to find probability.
Answer:
The correct answer of this question is the population standard deviation and the sample size is large.
Explanation:
Given - A random sample from normal distribution the method .
The sample mean has a normal distribution when the population distribution is normal.
The Central Limit Theorem predicts that our sampling distribution will resemble a normal distribution because our sample size is bigger than 30. The normal distribution will be used to find probability because we know the population standard deviation and the sample size is large.
