2. Evaluate the following statement. To answer this question please state the Central Limit Theorem and explain why central limit theorem is so important. The samples mean of a random sample of n observations from a normal population with mean u and variance o2 is a sampling statistics. The sample mean is normally distributed with mean u and variance oʻ/n due to central limit theorem.

Law of Large Numbers, Central Limit Theorem, and Confidence Intervals 1. (15 points) In an exercise, your Professor generated random numbers in Excel. The mean is supposed to be 0.5 because the numbers are supposed to be spread at randonm between 0 and 1. I asked the software to generate samples of 100 random numbers repeatedly. Here are the sample means x for 50 samples of size 100: 0.532 0.450 0.481 0.508 0.510 0.530 0.4990.4610.5430.490 0.497 0.5520.473 0.425 0.4490.507 0.472...

According to the central limit theorem, in order to assume a normal distribution for our sample mean if σ is unknown, we must have a sample size greater than ____.

Asked what the central limit theorem says, a student replies, "As you take larger and larger samples from a population, the histogram of the sample values looks more and more Normal." No. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample's mean. Yes. This is exactly what the theorem says. No. As you take larger and larger samples the histogram of the sample values looks less Normal.
