... about N / 2 observations to be greater than m, and about N / 2 observations to be less than m. So suppose x = number of observations > m. We can actually calculate the Binomial probability of having at least x observations out of N, when the probability that any observation will be > m is 50%. ...

With the standard medications, this proportion is about 0.25. This proportion may be less with the new medication. The results from the two facilities are Facili ...

The test at significance level δ is performed by checking whether ᾱ0 ∈ [L1 , L2 ], where L1 is the lower 1 − δ confidence limit on the population mean and L2 the upper confidence limit. circ medtest performs a nonparametric test of the hypothesis H0 that the m ...

If either population (treatment) distribution has unknown shape and the corresponding sample size is less than 30, use a graph of the sample data to assess the Normality of the population (treatment) distribution. Do not use two-sample t procedures if th ...
