Please answer all. Thank you. A 95 percent confidence interval for the mean can be interpreted mean that A.) if all possible samples are taken and confidence intervals are calculated, 95 percent of those interval would include the true population mean somewhere in the interval. B.) you can be 95 percent confident that you have selected sample whose interval does not include the population mean. C.) if all possible population are taken and confidence interval are calculated, 95 percent of those interval would include the true sample mean somewhere in their interval. D.) if all possible samples are taken and confidence intervals are calculated,95 percent of those interval would include the sample mean somewhere in their interval. When estimating the population mean with a small sample. The t-distribution may be used with ____ degree of freed
