    I need the completed and correct answer asap. thank you A 95% confidence interval for a population mean is from 101 to 104. What can we conclude from this? For 95% of all possible samples from this population, the confidence interval calculation will produce an interval contaming the population mean, so, based on this sample, we believe the population mean is between 101 and 104 The population mean is between 101 and 104 95% of all possible samples from this...
