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.

3.27. Problem. (Section 11.5) The following are applications of Theorem 11.6 or the Central Limit Theorem. (a) Determine the distribution of (1/5)X1 + (2 /5)X2 + (2/5)X3 if X1, X2 and X3 are independent normal distributions with µ = 2 and σ = 3. (b) The weight (kg) of a StarBrite watermelon harvested under certain environmental conditions is normally distributed with a mean of 8.0 with standard deviation of 1.9. Suppose 24 StarBrite watermelons grown in these conditions are harvested;...
