Answer #1

This is a False statement

In a normal distribution at 95% confidence interval from sample mean we add or subtract 1.96 times the standard error to calculate the confidence interval of the population mean on the basis of sample mean and the sample size but it doesn't say anything about the sample . Hence this statement is false.
