MTH 380 Lecture Notes - Lecture 7: Central Limit Theorem, Standard Deviation, Sampling Distribution
Document Summary
Ch. 7. 3, the central limit theorem and the sample mean. Packages of food whose average weight is 454 grams with a standard deviation of 17 grams are shipped in boxes of 24 packages. If the package weights are approximately normally distributed, what is the probability that a box of 24 packages will weigh more than. 7. 3, 29, p. 263: a filling machine puts an average of = 200 ml (milliliters) of coffee in cups, with standard deviation = 20 ml. One hundred cups filled by machine are selected at random. Find probability that the mean amount x of coffee per one cup in the sample of size n = 100 is less than 198 ml. If a random sample of 16 balls is selected, what is probability that sample mean will be within 0. 04 inches from the mean: ch. A bottler of soft drinks packages cans in six packs.
