The next step is to determine for each observation the corresponding quantile of the normal distribution that has the same mean and the standard deviation as the data. The following Excel function is a convenient way to determine the normal (i/(n+1)) th quantile, denoted as x’(i). x’(i) = NORMINV(i/(n+1), sample mean, sample standard ...

The sample mean response was 3.92 and the sample standard deviation was 1.57. Find a 90% confidence interval for the population mean response. In this case we have a large sample, so we can use Formula #1. The sample standard deviation s is used as a good estimate of the (unknown) population parameter (.
