The Law of Large Numbers (LLN) saysO The distribution of the sample mean should approximate a normal distribution as the sample size increases.O The mean obtained from a large sample should be equal to the population mean.O The sample means vary from sample to sample and are never equal to the population mean.O The mean obtained from a large sample should be close to the population mean, and will tend to become closer as more samples are collected.limpi

Information needed for the next two problems: A bored statistician is interested in researching length of commercial breaks on cable channels (ESPN, TNT, etc.) and comparing them to the length of commercial breaks on the networks (ABC, CBS, NBC, FOX). She times a random sample of commercials from each of the two types of broadcasts which are assumed to be normally distributed. Source n Mean(min.) Std. Dev. (min.) Cable 15 2.36 0.16 Network 12 2.18 0.13 Based on your previous answer for the upper bound and assuming the lower bound ratio of variances of cable to network is 0.5531, your conclusion about the spread of the variances of cable vs network commercials is O 1 is in the interval so statistically the same O O is in the interval so statistically the same O 1 is not in the interval so statistically different O O is in the interval so statistically not the same O 1 is in the interval so statistically not the same
4. Which proportion of a normal distribution is located between the mean and z = +1.40? 5. A vertical line drawn through a normal distribution at z = +2.11 separates the distribution into two sections, the body and the tail. Which proportion of the distribution is in the tail?
Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about ? = 28 ml/kg.† Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows. 32 25 42 34 32 39 31 I need help with sketching the distribution (d) and (e)

The finite population correction is most useful for which of the following? a. It adjusts the estimated mean when the sample size is a large fraction of the population size. b. It adjusts the standard error of the mean when the sample size is a small fraction of the population size. c. It adjusts the estimated mean when the sample size is a small fraction of the population size. d. It adjusts the standard error of the mean when the sample size is a large fraction of the population size.
Can a normal approximation be used for a sampling distribution of sample means from a population with u = 55 and o = 10, when n = 4? Answer E Tables E Keypad Keyboard Shortcuts O Yes, because the mean is greater than 30. O Yes, because the sample size is less than 30. O No, because the sample size is less than 30. O No, because the standard deviation is too small.
