Suppose we use statistical procedures and we find a 98% confidence interval for the true
value of the population parameter, $\mu$, as follows:
$627.73 \pm 50.64$
Which conclusion is correct?
O The true value of the population mean is 627.73.
O We're 98% confident that the true value of the population mean is 627.73.
O We're 98% confident that the true value of the population mean is between 526.45 and
729.01.
O The true value of the population mean is between 577.09 and 678.37.
O We're 98% confident that the true value of the population mean is between 577.09 and
678.37.
