Question 11 (5 points) Saved The sampling distribution of the mean becomes approximately normally distributed whern which of the following conditions is met? The standard deviation of the population is large. The sample size is large The population Distribution is not symmetric A single random sample is drawn from the population. Question 12 (10 points) Saved You select a sample of 100 and find a mean of 60 and a standard deviation of 12. What is the...

Which of the following statements about the sampling distribution of the sample mean, x-bar, is not true? The distribution is normal regardless of the shape of the population distribution, as long as the sample size,n, is large enough. The distribution is normal regardless of the sample size, as long as the population distribution is normal. The distribution's mean is the same as the population mean. The distribution's standard deviation is smaller than the population standard deviation. All of the above...

The Central Limit Theorem tells us that the sampling distribution of the sample mean can be approximated with a normal distribution for “large”n as n gets bigger, the sample data becomes more like the normal distribution if the data comes from an (approximately) normally distributed population, then the sample mean will also be (approximately) normally distributed the minimum variance unbiased estimator is the "best" estimator for a parameter
