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...

1. If X is non-normal and n<30, then the sampling distribution of standardized X-bar is: t (n-1) approximately Z unknown binomial 2. A statistician wants to estimate the mean loss suffered by Delta pilots in the labor negotiations to lower Delta salaries to within $2500 with 95% confidence. From a first small survey, the standard deviation of the loss is estimated at $10,000. What size sample should the statistician select? 1206 44 7 None of the above 3. The difference...
