... Red wine, in moderation Drinking red wine in moderation may protect against heart attacks. The polyphenols it contains act on blood cholesterol and thus are a likely cause. To test the hypothesis that moderate red wine consumption increases the average blood level of polyphenols, a group of nine ra ...

5.3 The Central Limit Theorem
... Central Limit Theorem • Suppose we take many random samples of size n for a variable with any distribution--For large sample sizes: 1. The distribution of means will be approximately a normal distribution. 2. The mean of the distribution of means approaches the population mean, . 3. The standard d ...

... Percent plant cover was measured in 16 randomly chosen areas (10 m sq) at the site. (8) a. What is the population to which you wish to make inference? What is a symbol for the mean of that population? The population is the set of coverage percentages of all 10x10 m square areas in the entire site. T ...
