Unformatted text preview: Where is the estimated mean and S 2 is the estimated variance based on n random observations. The above statistic is distributed as a t-distribution with parameter d.f. = ν = (n-1). If the absolute value of the computed T-statistic is “too large" compared with the critical value of the t-table, then one rejects the claimed value for the population's mean. This test could also be used for testing similar claims for other unimodal populations including those with discrete random variables , such as proportion, provided there are sufficient observations (say, over 30)....
