Part III. Exponential Rvs & the Central Limit Theorem a) Imagine sampling 5 values from Exp(5), an exponential distribution with rate 5. What should be the expected value (mean) of this sample? You should use the CLT (central limit theorem) and should not need to do any coding to answer this. Answer: Check Part III.

Demonstrate Central Limit Theorem(CLT) of the sample mean by sampling a 100 uniform distribution data with 50 variables. Verify the result by computing the sample mean, sample variance and sketch the histogram on Excel/Megastat. Hint: Generate 100 datasets of 50 variables and calculate 50 sample means to determine the distribution of X̅ and SX̅. It should converge to a model that we’ve learned in class.

True or False: the central limit theorem states that the sampling distribution of the sample mean is approximately normal whenever the population from which we are sampling is normally distributed Assume that 14% of the items produced in an assembly line operation are defective, but that the firm’s production manager is not aware of this situation. Assume firtber that the wuality assurance department to determine the quality of the assembly operation tests 50 parts. What is the probability that the...

8. Using Minitab to illustrate the Central Limit Theorem (CLT), the CLT tells us about the sampling distribution of the sample mean. With Minitab we can easily "sample" from a population with known properties (4,0 , shape). a. Our population consists of integer values X from 1 through 8, all equally likely P(x) = 1/8; x = 1, 2, 3, 4, 5, 6, 7, 8 o = 2.29 Using methods from the beginning of Chapter 4 in the textbook, find...

Applying the Central Limit Theorem: The amount of contaminants that are allowed in food products is determined by the FDA (Food and Drug Administration). Common contaminants in cow milk include feces, blood, hormones, and antibiotics. Suppose you work for the FDA and are told that the current amount of somatic cells (common name "pus") in 1 cc of cow milk is currently 750,000 (note: this is the actual allowed amount in the US!). You are also told the standard deviation...
