Applying the Central Limit Theorem, suppose that personal computers (PC) have a mean of weight of 7.5 pounds with a standard deviation of 1.1 pounds. If you take a sample of the weight of 50 different brands of PC, the sample standard deviation is: Select one: a. 7.5 1.1 7.51.1 b. 1.1 50 √ 1.150 c. 7.5+1.1 7.5+1.1

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...

Use the central limit theorem to find the mean and standard error of the mean of the indicated sampling distribution. Then sketch a graph of the sampling distribution. The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 107 pounds and a standard deviation of 39.1 pounds. Random samples of size 15 are drawn from this population and the mean of each sample is determined.

This week we’ve introduced the central limit theorem. According to the central limit theorem, for all samples of the same size n with n>30, the sampling distribution of x can be approximated by a normal distribution. In your initial post use your own words to explain what this theorem means. Then provide a quick example to explain how this theorem might apply in real life. At last, please share with us your thoughts about why this theorem is important.
